Abstract

PURPOSE: To detect trouble occurrence in a demodulator without requiring a monitoring demodulator by connecting an equalizer to the input terminal of a demodulator, which is a monitored circuit, to equalize input signals and giving a prescribed bias to the demodulated output to compare it in a comparator and detecting positive or negative components in a detector.
