Abstract
A color signal processing apparatus comprising a first delay circuit for delaying an input chroma signal; a second delay circuit for delaying an output of the first delay circuit; a plurality of gain control circuits for controlling the amplitudes of the input chroma signal and the outputs of the first and second delay circuits, respectively; and an operating circuit for operating the gain-controlled amplitudes of the input chroma signal and the outputs of the first and second delay circuits, wherein the phases of the outputs of the first and second delay circuits are matched with the phase of the input chroma signal.
