Abstract
A circuit for separating the luminance signal and chrominance signal from a composite video signal in a digital signal processing system using adaptive 2H comb filters. The circuit according to the present invention generates luminance difference signals, and chrominance difference signals from the horizontal scanning lines of a composite video signal for the purpose of detecting the correlation of the chrominance difference signals as well as the correlation of the luminance difference signals to generate a correlation coefficient. The chrominance signal is accurately separated from a composite video signal in response to the generated correlation coefficient.
