Abstract:

A phase demodulator for recovering the modulating wave from a phase-modulated wave. A frequency divider is provided to divide the phase-modulated wave in frequency to produce a phase-modulated subharmonic wave which is compared in a phase comparator with a signal produced by passing the phase-modulated subharmonic wave through a synchronous filter set at its carrier frequency. The filtered output of the phase comparator is proportional to the amplitude of the modulating wave. Author
