  • Noise Elimination (AREA)

Abstract

PURPOSE: To eliminate noises generated in a FM-demodulated signal effectively, by providing a method which supplies a FM signal to be demodulated to a phase comparator as one input FM signal and another method which supplies a FM signal to be demodulated to a variable high-pass filter of the secondary characteristics.
