Method and apparatus for smoothing out phase fluctuations in a monitored signal

摘要

A method and apparatus for smoothing out phase fluctuations in a monitored input signal by: detecting the partial-cycle differences in phase between the input signal and a reference signal, and generating a first error signal representing the partial-cycle differences in phase; detecting full-cycle differences in phase between the input signal and the reference signal, and generating a second error signal representing the full-cycle differences in phase; and utilizing the first and second error signals for smoothing out the phase fluctuations in the input signal.
