ABSTRACT:
For improving the frequency characteristic of a color television signal, particularly one in which the chrominance component thereof is provided with a bandwidth substantially narrower than that of the luminance component, the luminance component is used to generate a control signal which is proportional to the lack of registration between low and high frequency portions of the luminance component spectrum, and the control signal thus obtained selectively increases and decreases a delay applied to the relatively narrow-bandwidth chrominance component to substantially align its excursions with the excursions of the relatively wide bandwidth luminance component.
