Abstract
PURPOSE: To prevent the phase shift and distortion in the waveform for chroma signal, by separating the luminance signal and chroma signal with operation.
CONSTITUTION: The composit video signal including luminance signal and chroma signal is picked up from the emitter of the transistor Tr3 of the amplifying circuit 2, and the output at the low level is fed to the delay circuit 4. The video signal delayed at Tr7 and the video signal not delayed are added and only the luminance signal is picked up through cancellation of the chroma signal components. On the other hand, at Tr9, the video signal delayed from the video signal not delayed is subtracted and the chroma signal is doubled, and at Tr12, the luminance signal is subtracted and only the chroma signal component is isolated.
