Abstract
A demodulator for PSK-FM double modulated carrier signals in which the carrier signal is 2.sup.N phase modulated by a main signal and frequency modulated by a sub-signal. A clock component is extracted from the received double-modulated carrier signal and the carrier signal sampled in accordance therewith. The amplitude of the output of the sampling gate is limited prior to frequency multiplication by 2.sup.N. A frequency modulated component is then demodulated from the multiplied signal.
