In order to overcome this problem of the particle filter, we propose a novel filtering method called the genetic filter.

The standard Bernoulli filter often underestimates the number of the targets.

By employing the particle flow filter, the computational speed of the Bernoulli filters is significantly improved. In addition, the GPF Bernoulli filter provides more accurate estimation compared with that of the standard Bernoulli filter.

The computation of the Kalman filter gain requires the inversion of an m x m matrix in every iteration. In this paper, a variation of the Kalman filter eliminating the Kalman filter gain is proposed. In the time varying case, the elimination of the Kalman filter gain requires the inversion of an n x n matrix and the inversion of an m x m matrix in every iteration. In the time invariant case, the elimination of the Kalman filter gain requires the inversion of an n x n matrix in every iteration.

A robust filter is required to cope up with the problem of unpredictable discontinuities and colored noises associated with low cost sensors.

Unscented Kalman filter has a problem of Cholesky matrix factorization at each step which is a very unstable operation.

The filter consumes 1.5mW from a supply voltage of 0.9V. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Common-mode%20feedback" title="Common-mode feedback">Common-mode feedback</a>, <a href="https://publications.waset.org/search?q=continuous-time" title=" continuous-time"> continuous-time</a>, <a href="https://publications.waset.org/search?q=fully%0Adifferential%20transconductor" title=" fully differential transconductor"> fully differential transconductor</a>, <a href="https://publications.waset.org/search?q=Gm-C%20topology" title=" Gm-C topology"> Gm-C topology</a>, <a href="https://publications.waset.org/search?q=low-voltage" title=" low-voltage"> low-voltage</a> </p> <a href="https://publications.waset.org/14428/a-low-voltage-tunable-channel-selection-filter-for-wimax-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14428/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14428/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14428/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14428/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14428/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14428/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14428/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14428/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14428/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14428/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14428.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1608</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">791</span> Research on Laws and Regulations of Sustainable Construction in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Wei%20Zhang">Wei Zhang</a>, <a href="https://publications.waset.org/search?q=Jing%20Dong"> Jing Dong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduced the status quo of laws and regulations of sustainable construction in China and investigated the existing problems of current laws and regulations through person-interviews in Beijing, Shanghai, Chongqing and Shenzhen in China.

Pourtakdoust</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extended Kalman Filter (EKF) is probably the most widely used estimation algorithm for nonlinear systems. However, not only it has difficulties arising from linearization but also many times it becomes numerically unstable because of computer round off errors that occur in the process of its implementation. To overcome linearization limitations, the unscented transformation (UT) was developed as a method to propagate mean and covariance information through nonlinear transformations. Kalman filter that uses UT for calculation of the first two statistical moments is called Unscented Kalman Filter (UKF). Square-root form of UKF (SRUKF) developed by Rudolph van der Merwe and Eric Wan to achieve numerical stability and guarantee positive semi-definiteness of the Kalman filter covariances. This paper develops another implementation of SR-UKF for sequential update measurement equation, and also derives a new UD covariance factorization filter for the implementation of UKF. This filter is equivalent to UKF but is computationally more efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Unscented%20Kalman%20filter" title="Unscented Kalman filter">Unscented Kalman filter</a>, <a href="https://publications.waset.org/search?q=Square-root%20unscentedKalman%20filter" title=" Square-root unscentedKalman filter"> Square-root unscentedKalman filter</a>, <a href="https://publications.waset.org/search?q=UD%20covariance%20factorization" title=" UD covariance factorization"> UD covariance factorization</a>, <a href="https://publications.waset.org/search?q=Target%20tracking." title=" Target tracking."> Target tracking.</a> </p> <a href="https://publications.waset.org/8622/ud-covariance-factorization-for-unscented-kalman-filter-using-sequential-measurements-update" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/8622/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/8622/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/8622/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/8622/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/8622/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/8622/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/8622/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/8622/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/8622/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/8622/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/8622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4846</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">786</span> Tunable Photonic Microwave Bandpass Filter Based on EOPM and VPBS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=R.%20Heydari">R.

The proposed filter consists of multiple units of ANF connected in parallel structure; each unit is governed by two ordinary differential equations. The frequency estimation is carried out based on the output of these units. The simulation and experimental results show the ability of the proposed tracking scheme to accurately estimate harmonics. The proposed filter was implemented digitally in TMS320F2808 and used in the control of hybrid active power filter (HAPF).

The technique is based on frequency transformation in the s-domain, bilinear z-transform with pre-warping frequency, inverse bilinear transformation and a very useful application of the Pascal’s triangle that simplifies computing and enables calculation by hand when transforming from one filter to another. This paper will introduce two methods to transform a filter into a digital filter: frequency transformation from the s-domain into the z-domain; and frequency transformation in the z-domain. Further, two Pascal matrix equations are derived: an analogue to digital filter Pascal matrix equation and a digital to digital filter Pascal matrix equation. These are used to design a desired digital filter from a given filter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Frequency%20transformation" title="Frequency transformation">Frequency transformation</a>, <a href="https://publications.waset.org/search?q=Bilinear%20z-transformation" title=" Bilinear z-transformation"> Bilinear z-transformation</a>, <a href="https://publications.waset.org/search?q=Pre-warping%20frequency" title=" Pre-warping frequency"> Pre-warping frequency</a>, <a href="https://publications.waset.org/search?q=Digital%20filters" title=" Digital filters"> Digital filters</a>, <a href="https://publications.waset.org/search?q=Analog%20filters" title=" Analog filters"> Analog filters</a>, <a href="https://publications.waset.org/search?q=Pascal%E2%80%99s%0D%0Atriangle." title=" Pascal’s triangle."> Pascal’s triangle.</a> </p> <a href="https://publications.waset.org/10003378/frequency-transformation-with-pascal-matrix-equations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003378/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003378/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003378/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003378/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003378/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003378/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003378/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003378/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003378/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003378/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003378.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1915</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">780</span> Supremacy of Differential Evolution Algorithm in Designing Multiplier-Less Low-Pass FIR Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Abhijit%20Chandra">Abhijit Chandra</a>, <a href="https://publications.waset.org/search?q=Sudipta%20Chattopadhyay"> Sudipta Chattopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this communication, we have made an attempt to design multiplier-less low-pass finite impulse response (FIR) filter with the aid of various mutation strategies of Differential Evolution (DE) algorithm.

Performance of the proposed filter has been evaluated in terms of its frequency response and associated hardware cost. Supremacy of our approach has been substantiated by comparing our result with many of the existing multiplier-less filter design algorithms of recent interest. It has also been demonstrated that DE-optimized filter outperforms Genetic Algorithm (GA) based design by a large margin.  Hardware efficiency of our algorithm has further been validated by implementing those filters on a Field Programmable Gate Array (FPGA) chip.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Convergence%20speed" title="Convergence speed">Convergence speed</a>, <a href="https://publications.waset.org/search?q=Differential%20Evolution%20%28DE%29" title=" Differential Evolution (DE)"> Differential Evolution (DE)</a>, <a href="https://publications.waset.org/search?q=error%20histogram" title=" error histogram"> error histogram</a>, <a href="https://publications.waset.org/search?q=finite%20impulse%20response%20%28FIR%29%20filter" title=" finite impulse response (FIR) filter"> finite impulse response (FIR) filter</a>, <a href="https://publications.waset.org/search?q=total%20power%20of%20two%20%28TPT%29" title=" total power of two (TPT)"> total power of two (TPT)</a>, <a href="https://publications.waset.org/search?q=zero-valued%20filter%20coefficient%20%28ZFC%29." title=" zero-valued filter coefficient (ZFC)."> zero-valued filter coefficient (ZFC).</a> </p> <a href="https://publications.waset.org/9997723/supremacy-of-differential-evolution-algorithm-in-designing-multiplier-less-low-pass-fir-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997723/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997723/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997723/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997723/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997723/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997723/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997723/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997723/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997723/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997723/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2155</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">779</span> SystemC Modeling of Adaptive Least Mean Square Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kyu%20Han%20Kim">Kyu Han Kim</a>, <a href="https://publications.waset.org/search?q=Soon%20Kyu%20Kwon"> Soon Kyu Kwon</a>, <a href="https://publications.waset.org/search?q=Heung%20Sun%20Yoon"> Heung Sun Yoon</a>, <a href="https://publications.waset.org/search?q=Jong%20Tae%20Kim"> Jong Tae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we demonstrate the adaptive least-mean-square (LMS) filter modeling using SystemC.

This paper proposes a blind channel estimation method namely IMM (Interactive Multiple Model) Based Kalman algorithm for UWB OFDM systems. IMM based Kalman filter is proposed to estimate frequency selective time varying channel. In the proposed method, two Kalman filters are concurrently estimate the channel parameters. The first Kalman filter namely Static Model Filter (SMF) gives accurate result when the user is static while the second Kalman filter namely the Dynamic Model Filter (DMF) gives accurate result when the receiver is in moving state. The static transition matrix in SMF is assumed as an Identity matrix where as in DMF, it is computed using Yule-Walker equations. The resultant filter estimate is computed as a weighted sum of individual filter estimates. The proposed method is compared with other existing channel estimation methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Channel%20estimation" title="Channel estimation">Channel estimation</a>, <a href="https://publications.waset.org/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/search?q=UWB" title=" UWB"> UWB</a>, <a href="https://publications.waset.org/search?q=Channel%20model" title=" Channel model"> Channel model</a>, <a href="https://publications.waset.org/search?q=AR%20model" title=" AR model"> AR model</a> </p> <a href="https://publications.waset.org/13295/imm-based-kalman-filter-for-channel-estimation-in-mb-ofdm-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13295/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13295/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13295/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13295/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13295/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13295/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13295/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13295/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13295/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13295/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13295.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2090</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">777</span> New Nonlinear Filtering Strategies for Eliminating Short and Long Tailed Noise in Images with Edge Preservation Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=E.%20Srinivasan">E. Srinivasan</a>, <a href="https://publications.waset.org/search?q=D.%20Ebenezer"> D. Ebenezer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Midpoint filter is quite effective in recovering the images confounded by the short-tailed (uniform) noise. It, however, performs poorly in the presence of additive long-tailed (impulse) noise and it does not preserve the edge structures of the image signals. Median smoother discards outliers (impulses) effectively, but it fails to provide adequate smoothing for images corrupted with nonimpulse noise. In this paper, two nonlinear techniques for image filtering, namely, New Filter I and New Filter II are proposed based on a nonlinear high-pass filter algorithm. New Filter I is constructed using a midpoint filter, a highpass filter and a combiner. It suppresses uniform noise quite well. New Filter II is configured using an alpha trimmed midpoint filter, a median smoother of window size 3x3, the high pass filter and the combiner. It is robust against impulse noise and attenuates uniform noise satisfactorily. Both the filters are shown to exhibit good response at the image boundaries (edges). The proposed filters are evaluated for their performance on a test image and the results obtained are included. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Image%20filters" title="Image filters">Image filters</a>, <a href="https://publications.waset.org/search?q=Midpoint%20filter" title=" Midpoint filter"> Midpoint filter</a>, <a href="https://publications.waset.org/search?q=Nonlinear%20filters" title=" Nonlinear filters"> Nonlinear filters</a>, <a href="https://publications.waset.org/search?q=Nonlinear%20highpass%20filter" title=" Nonlinear highpass filter"> Nonlinear highpass filter</a>, <a href="https://publications.waset.org/search?q=Order-statistic%20filters" title=" Order-statistic filters"> Order-statistic filters</a>, <a href="https://publications.waset.org/search?q=Rank-order%20filters." title=" Rank-order filters."> Rank-order filters.</a> </p> <a href="https://publications.waset.org/15445/new-nonlinear-filtering-strategies-for-eliminating-short-and-long-tailed-noise-in-images-with-edge-preservation-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15445/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15445/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15445/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15445/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15445/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15445/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15445/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15445/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15445/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15445/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15445.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1449</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">776</span> Design of an Efficient Retimed CIC Compensation Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Vishal%20Awasthi">Vishal Awasthi</a>, <a href="https://publications.waset.org/search?q=Krishna%20Raj"> Krishna Raj </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Unwanted side effects because of spectral aliasing and spectral imaging during signal processing would be the major concern over the sampling rate alteration. Multirate-multistage implementation of digital filter could come about a large computational saving than single rate filter suitable for sample rate conversion. This implementation can further improve through high-level architectural transformation in circuit level. Reallocating registers and  relocating flip-flops across logic gates through retiming certainly a prominent sequential transformation technology, that optimize hardware circuits to achieve faster clocking speed without affecting the functionality. In this paper, we proposed an efficient compensated cascade Integrator comb (CIC) decimation filter structure that analyze the consequence of filter order variation which has a retimed FIR filter being compensator while using the cutset retiming technique and achieved an improvement in the passband droop by 14% to 39%, in computation time by 38.04%, 25.78%, 12.21%, 6.69% and 4.44% and reduction in path delay by 62.27%, 72%, 86.63%, 91.56% and 94.42% of 3, 6, 8, 12 and 24 order filter respectively than the non-retimed CIC compensation filter.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Multirate%20Filtering" title="Multirate Filtering">Multirate Filtering</a>, <a href="https://publications.waset.org/search?q=CIC%20decimation%20filter" title=" CIC decimation filter"> CIC decimation filter</a>, <a href="https://publications.waset.org/search?q=Compensation%20theory" title=" Compensation theory"> Compensation theory</a>, <a href="https://publications.waset.org/search?q=Retiming" title=" Retiming"> Retiming</a>, <a href="https://publications.waset.org/search?q=Retiming%20algorithm" title=" Retiming algorithm"> Retiming algorithm</a>, <a href="https://publications.waset.org/search?q=Filter%20order" title=" Filter order"> Filter order</a>, <a href="https://publications.waset.org/search?q=Synchronous%20dataflow%20graph." title=" Synchronous dataflow graph."> Synchronous dataflow graph.</a> </p> <a href="https://publications.waset.org/9998624/design-of-an-efficient-retimed-cic-compensation-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998624/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998624/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998624/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998624/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998624/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998624/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998624/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998624/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998624/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998624/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998624.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3706</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">775</span> A Low Noise Microwave Filter with Minimum Distortion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Cheng%20Yuan%20Hung">Cheng Yuan Hung</a>, <a href="https://publications.waset.org/search?q=Min%20Hang%20Weng"> Min Hang Weng</a>, <a href="https://publications.waset.org/search?q=Siang%20Wen%20Lan"> Siang Wen Lan</a>, <a href="https://publications.waset.org/search?q=Wei%20Yu%20Chen"> Wei Yu Chen</a>, <a href="https://publications.waset.org/search?q=Hung%20Wei%20Wu"> Hung Wei Wu</a>, <a href="https://publications.waset.org/search?q=Chun%20Yueh%20Huang"> Chun Yueh Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a low noise microwave bandpass filter (BPF) is presented.
