ABSTRACT:
A video reproduction signal-processing circuit is an integrated circuit and is incorporated in a video tape recorder. In this integrated circuit, a dropout-detecting circuit generates a dropout signal, and a limiter circuit and a wave-shaping circuit jointly output a noncorrelation/correlation signal. The dropout signal and the noncorrelation/correlation signal are first added together by an adder circuit, and are then output from the integrated circuit through a single output terminal.
