摘要：A high frequency band signal is separated from a demodulated video signal and then is supplied to a noise clipping circuit in which black peak portions of the signal exceeding a predetermined black signal level are clipped.
The resulting clipped output is combined with a low frequency band signal also separated from the demodulated video signal by which a negative going overshoot noise caused at the beginning of the horizontal blanking period is eliminated, and accordingly the signal to the noise ratio is improved and disturbance of synchronization is avoided.
