ABSTRACT:
A Y/C separation apparatus separating a luminance signal and a chrominance signal from a composite color television signal includes a high band level detection circuits for detecting a high band level of each input signal and a judge circuit for controlling Y/C separation and selects one of filters to pass the input signal according to the high band levels detected by the high band level detection circuits and controls a separated chrominance signal component. As a result, when the high band level is small, a horizontal BPF is selected and even when the input signal is a black or white video signal without chrominance signal, dot interference is not conspicuous.
