ABSTRACT:
A phase detector responsive to a first signal having a carrier frequency and a second signal close to the carrier frequency, including a carrier suppression circuit which produces a carrier suppressed signal from the first and second signals, and a mixer responsive to the carrier suppressed signal and the carrier frequency to produce an output signal corresponding to the phase difference between the first and second signals.
