Abstract
PURPOSE: To make it possible to remove modulation audio signals mixed into demodulation video signals, by clipping modulation audio signals sampled from demodulated video signals within a range, where the carrier wave is not saturated, and using correction signals.
CONSTITUTION: Demodulated video signals are divided into two at point (1), and one and the other are supplied to video transmission system 6 and correction signal forming circuit 7 respectively. Band components including the carrier wave of modulation audio signals are sampled by correction signal forming circuit 7, and these sampled signals are clipped within a range, where the carrier wave is not saturated by clip circuit 10. These clipped signals are added to demodulated video signals in mixer circuit 14, thus outputting video signals where modulation audio signals are removed.
