Digital phaselock demodulator

摘要

A digital phaselock demodulator suitable for demodulating a variety of phase or frequency modulated signals including an FM'd VOR signal component. A digital phase detector receives the modulated input signal and a feedback signal, and outputs demodulated signal. Two sets of digital words of different word rates are provided wherein one set is reversible in order as a function of phase between input and feedback signals. Digital word comparison occasions the feedback signal.
