Abstract

본 발명은 클램프 신호 생성 동작 제어방법에 관한 것으로, 종래에는 클램프 신호를 생성하기 위한 별도의 회로가 구성되어야만 했었다. 본 발명은 파스날 컴퓨터로부터 전송되는 수평 동기신호에 의해 비디오 신호를 처리하는 비디오 앰프에 클램프 신호를 생성하여 출력하므로서, 전체적인 구성을 단순화시킬 수 있음은 물론이고 안정된 클램프 신호를 비디오 앰프에 공급할 수 있는 효과가 있다.The present invention relates to a method for controlling a clamp signal generation operation, and in the related art, a separate circuit for generating a clamp signal had to be configured. The present invention generates and outputs a clamp signal to a video amplifier processing a video signal by a horizontal synchronization signal transmitted from a personal computer, thereby simplifying the overall configuration and supplying a stable clamp signal to the video amplifier. It works.

Claims (1)

수평 동기신호에 의해 클램프 신호를 생성하는 클램프 신호 생성 동작 제어방법에 있어서, 수평 동기신호의 극성을 판정하여 그 결과 양극성이면 "하이"레벨에서 "로우"레벨로 전환된 후 소정시간 동안 클램프 신호를 출력하고, 음극성이면 "로우"레벨에서 "하이"레벨로 전환된 후 소정시간 동안 클램프 신호를 출력하도록 구성되어짐을 특징으로 하는 클램프 신호 생성 동작 제어방법.A clamp signal generation operation control method for generating a clamp signal by a horizontal synchronizing signal, wherein the polarity of the horizontal synchronizing signal is determined, and if it is bipolar, the clamp signal is generated for a predetermined time after switching from the "high" level to the "low" level. Outputting the clamp signal for a predetermined time after the transition from the " low " level to the " high " level of the negative polarity. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
