Abstract :
In binary FSK modulation schemes the transition between the two frequencies f0 representing a ZERO and f1 representing a ONE is governed by the shape of the input pulse as it makes its transition from a ZERO to a ONE. Through the use of an optimum filter, it is possible to shape the pulse in such a way as to maximize the speed of transition from f0 to f1 while maintaining signal energy outside of the channel to specified small levels. In this paper, we describe a procedure for finding optimum filters for several important types of FSK modulation
