ABSTRACT:
A demodulator for a phase coherent frequency shift keyed signal has a master clock which generates a signal having a plurality of pulses during each half of the bit internal of the FSK signal. A detector determines during which master clock pulse within several groups of X number of pulses the most transitions occur in the received signal. Based on the determined clock pulse, samples taken in each of two consecutive half-bit intervals of the FSK signal are selected for comparison to produce the demodulator output signal.
