Peony TC-483D color TV decoding circuit consists of two parts: the IC_ (601) and its peripheral circuits consisting of color processing circuit and the IC_ (301) and its peripheral circuit brightness signal amplification and matrix circuit shown in Figure 1 1. Color Processing Circuit The task of the local color processing circuit is to remove the color difference signals (RY) and (BY) from the color full TV signal and send them to the luminance signal
