Penerima FM menggunakan detektor spesial untuk sinyal-sinyal FM sehingga memperlihatkan satu fenomena yang disebut "capture effect",di mana penala "menangkap" sinyal yang paling kuat dari dua stasiun dan menolak yang lain(bandingkan dengan situasi yang sama pada penerima AM,di mana kita dapat mendengar suara kedua stasiun tersebut bersamaan). Penguat switching frekuensi-radio dengan efisiensi tinggi dapat digunakan untuk mentransmisikan sinyal FM(dan sebarang sinyal amplitudo-konstan).Pada ukuran kekuatan tertentu(sinyal yang diukur pada antenna receiver),penguat switching tidak banyak menghabiskan daya baterai dan khusunya lebih murah dibanding penguat linear.Inilah kelebihan FM yang lain dibandingkan metode modulasi yang lain yang memrlukan penguat linear semisal,AM dan <a href="/wiki/QAM" class="mw-redirect" title="QAM">QAM</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Lihat_pula">Lihat pula</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Modulasi_frekuensi&veaction=edit&section=7" title="Sunting bagian: Lihat pula" class="mw-editsection-visualeditor"><span>sunting</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Modulasi_frekuensi&action=edit&section=7" title="Sunting kode sumber bagian: Lihat pula"><span>sunting sumber</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Modulasi_amplitudo" title="Modulasi amplitudo">Modulasi amplitudo</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Referensi">Referensi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Modulasi_frekuensi&veaction=edit&section=8" title="Sunting bagian: Referensi" class="mw-editsection-visualeditor"><span>sunting</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Modulasi_frekuensi&action=edit&section=8" title="Sunting kode sumber bagian: Referensi"><span>sunting sumber</span></a><span class="mw-editsection-bracket">]</span></span></div> <ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><a rel="nofollow" class="external text" href="http://ltrgm.et.itb.ac.id/wp-content/uploads/2016/03/buku_petunjuk.pdf">Modulasi dan Demodulasi Frekuensi</a></span> </li> </ol>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Diperoleh dari "<a dir="ltr" href="https://id.wikipedia.org/w/index.php?title=Modulasi_frekuensi&oldid=25224367">https://id.wikipedia.org/w/index.php?title=Modulasi_frekuensi&oldid=25224367</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Istimewa:Daftar_kategori" title="Istimewa:Daftar kategori">Kategori</a>: <ul><li><a href="/w/index.php?title=Kategori:Artikel_yang_layak_digabungkan_sejak_Juni_2016&action=edit&redlink=1" class="new" title="Kategori:Artikel yang layak digabungkan sejak Juni 2016 (halaman belum tersedia)">Artikel yang layak digabungkan sejak Juni 2016</a></li><li><a href="/wiki/Kategori:Elektronika" title="Kategori:Elektronika">Elektronika</a></li><li><a href="/wiki/Kategori:Teknologi_radio" title="Kategori:Teknologi radio">Teknologi radio</a></li><li><a href="/wiki/Kategori:Modem" title="Kategori:Modem">Modem</a></li><li><a href="/wiki/Kategori:Protokol_lapisan_fisik" title="Kategori:Protokol lapisan fisik">Protokol lapisan fisik</a></li><li><a href="/wiki/Kategori:Radio_amatir" title="Kategori:Radio amatir">Radio amatir</a></li><li><a href="/wiki/Kategori:Komunikasi_data" title="Kategori:Komunikasi data">Komunikasi data</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Kategori tersembunyi: <ul><li><a href="/wiki/Kategori:Artikel_dengan_parameter_tanggal_yang_tidak_valid_pada_templat" title="Kategori:Artikel dengan parameter tanggal yang tidak valid pada templat">Artikel dengan parameter tanggal yang tidak valid pada templat</a></li><li><a href="/wiki/Kategori:Artikel_yang_layak_digabungkan" title="Kategori:Artikel yang layak digabungkan">Artikel yang layak digabungkan</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> Halaman ini terakhir diubah pada 27 Januari 2024, pukul 01.58.</li> <li id="footer-info-copyright">Teks tersedia di bawah <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by-sa/4.0/deed.en">Lisensi Atribusi-BerbagiSerupa Creative Commons</a>; ketentuan tambahan mungkin berlaku.
