SOUND COMPENSATION CIRCUIT OF MULTI-T.V. RECEIVER

摘要

an intermediate frequency circuit means(20) outputting the frequency-modulated sound data by playing it, among the composite video signal picked-up through a tuner(1); a filter means(30) filtering the sound data outputted from the intermediate frequency circuit means(20) in some bandpass band; an integrating means(40) integrating the data outputted from the filter means(30); and a control means(50) controlling the operation of trap circuits(T1,T2) by the control signal outputted from the integrating means(40).
