Abstract
To improve the management of the frequency resource in the multi-channel section of the telecommunication system, the selectitve systems (SS) with high rectangularity of AFC are used. At that AFC and PFC for SS could have a complicated character [1]. In the given work the selective system with the high slope grade of AFC at its relatively smooth form was synthesized. The response of such a filter for PSK signal with the rectangular envelope of the elements was examined, and also the degree of squeezing from the adjacent channels at the relatively small overlap of filters AFC of the adjacent channels.
