Abstract

PURPOSE: To make the synchronous coupling between a picture and sound by supplying a video signal and sound signal after superposed each other as to the multiple synchronous coupling of TV signals.
CONSTITUTION: An input video signal after LPF10 and input sound signal after FM modulator 13 and BPF14 are mixed 11 after being band-limited respectively. The mixed output having been frequency-multiplied is supplied to video synchronous coupler 15, where equvalent delaying is done. The output of coupler 15 is passed through LPF16, BPF18 and FM demodulator 19 to obtain the original video signal and sound signal
