A demodulator is described which includes a hard limiter, reference generator and a phase determiner. The hard limiter produces a binary phase-modulated signal from an analog phase modulated input signal having a first frequency. The reference generator provides a binary reference signal having a second frequency generally equivalent to the first frequency. The phase determiner is operative during a sampling period and determines the phase between the phase-modulated and the reference binary signals during the sampling period.
