Abstract

PURPOSE: To make easy to see the noise band part of the video signal reproduced to the utmost, by providing the limitter circuit decreasing the amplitude of the noise band caused in the reproduced video signal than the amplitude of the reproduced video signal.
CONSTITUTION: In the video signal reproducing unit scanning and reproducing the tracks recording the video signal FM-modulated partly outsided or causing the noise band to the reproduced video signal with scanning reproduction over a plurality of tracks, the circuit 22 detecting the noise band part caused in the reproduced video signal and the limitter circuit 23 operating the noise band part with the output from this and reducing the amplitude at the noise band caused in the reproduced video signal than the amplitude of the reproduced video signal are provided, allowing to make easy to see the noise band of the video signal reproduced to the utmost.
