Determination of the selective filter responce to the frequency shift signal with the sine enveloping curve by the help of the orthogonal components method

There is studied passing of the frequency-shift keyed (FSK) sequence of radio pulse signals with the sine enveloping curve through the selective filter. The derived design relations for the filter response with the accuracy of up to a RF filling phase may be used in the process of development and investigation of the electronic systems (ES) of communication, radiolocalion and navigation. that use pseudorandom sequences with a frequency-shift modulation.
