Abstract

PURPOSE:To avoid remarkable noise, by detecting noise included in a television signal and controlling the amplitude of a burst signal and the band of a luminance signal according to the amount of noise. CONSTITUTION:A detection signal detecting a received television signal is applied to a terminal 1. This detected signal is applied to a band control circuit 2, noise amount detecting circuit 3, band pass filter 4 and synchronism separation circuit 5. The circuit 3 picks up a part without a video signal and a burst signal with sampling, and this output is converted into a DC signal at a DC circuit 8. This DC signal is applied to a burst amplitude control circuit 9 and a band control circuit 2.
