ABSTRACT:
An improved filter is provided for separating two interleaved signals such as a television chroma and luminance signal. Means are provided for detecting when the chroma of a first line is uncorrelated with the chroma of a second line. The apparatus will respond to this detection so as to minimize the uncancelled chroma produced when a line of video signal is uncorrelated with the previous line of video information.
