While propagating in the media, the deformation and evaluation of the signal in time and space take place and on the receiver we get a deformed signal. The present article is dedicated to studying the spacetime evolution of rectangular, sinusoidal, exponential and biexponential impulses via numerical experiment in the collisional, cold plasma. The presented method is not based on the Fourierpresentation of the signal. Analytically, we have received the general image depicting the spacetime evolution of the radio impulse amplitude that gives an opportunity to analyze the concrete results in the case of primary impulse. </abstract> <index>Open Science Index 128, 2017</index> </article>
