Claims (1)

  1. 콤포지트 비데오신호를 디지탈처리하는 색신호디코딩회로에 있어서, 콤포지트 비데오신호(가)는 A/D변화기(14)와 디지탈필터(18)를 순차거쳐 휘도신호(Y)와 색신호 (R-Y,B-Y)로 분리되고, 상기휘도신호(Y)는 매트릭스회로(24)에 인가되며 색신호(R-Y,B-Y)는 곱셈기 (20)(21)에 각각인가되어 동기검출기 (15)와 (16) 및 샘플링 클럭발생기 (17)에 의해 색동기되어 롬(19)에서 출력되는 신호 (a)(b)와 곱셈기(20)(21)에서 각각 곱해지고, 상기 곱셈기(20)(21)의 출력신호는 디지탈필터(22)(23)를 각각거쳐 순수한 색신호(R-Y)(B-Y)로 분리되어 매트릭스회로 (24)에 인가되고, 매트릭스회로(24)의 출력단으로는 R,G,B신호를 출력시키도록한 것을 특징으롬하는 디지탈 색신호디코딩회로.
