Adaptive comb filter.

摘要

Various filter circuits for a processing digitized color television signals are disclosed. Particularly, there are disclosed several embodiments of a luminance/chrominance signal separating filter (11) with which separated, digitized luminance and chrominance signals are derived with a minimum amount of interference therebetween by determining the direction from a given point in which there is a minimum amount of change in the digitized image signal. Also, there is disclosed a subnyquist sampling filter which operates upon this same principle. <IMAGE>
