Claims (2)
- 비데오 동기신호를 입력하여 위상과 펄스폭을 가변하여서 출력하는 위상과 폭 조절부(1)과, 상기한 위상과 폭 조절부(1)의 출력신호에서 펄스의 하강에지의 폭 즉, 하강시간을 짧게하는 적분회로(2)와, 상기한 적분회로(2)의 출력신호에 의해서 입력되는 동기 신호의 펄스의 상승시간과 펄스의 하강시간을 가변하여 출력하는 에지 조절부(3)로 이루어진 것을 특징으로 하는 비데오 동기신호의 펄스 조절회로.
- 제1항에 있어서, 위상 폭 조절부(1)는 비데오 동기 신호(In)를 입력하여 다이오드(D1)와 가변저항(R1) 및 접지된 콘덴서(C1)를 거쳐서 한 입력단이 접지된 오아게이트(OR)의 다른 입력단에 인가하고, 콘덴서(C1)에서 방전된 신호는 가변저항(R2)과 다이오드(D2)를 거쳐서 다이오드(D1)에 인가하도록 연결한 것을 특징으로 하는 비데오 동기신호의 펄스 조절회로.
