Abstract
A comb filter system for the separation of the luminance and chrominance components of an NTSC color television signal which analyzes the video signal on the television lines and detects luminance or color transistions in the vertical direction, and in response to the presence of one or both of such transitions, automatically either modifies or removes the comb filter, to minimize transient distortions in the reconstructed television picture. The system can be implemented in either the analog domain or the digital domain.
