Abstract
본 발명은 비디오신호의 샘플링회로에 관한 것으로, 종래에는 비디오신호를 샘플링하는 스위치를 구동시키는 클럭펄스부분이 샘플링하고자하는 신호와 연관성이 적어 샘플링할 부분을 정확히 결정할수 없는 문제점이 있었다.The present invention relates to a sampling circuit for a video signal. In the related art, a clock pulse portion for driving a switch for sampling a video signal has a low correlation with a signal to be sampled, so that a portion to be sampled cannot be accurately determined.
따라서 종래의 문제점을 해결하기 위하여 본 발명은 엔티에스씨(NTSC) 방식과 팔(PAL) 방식에 관계없이 샘플링할 비디오신호의 크기와 필요한 위치를 저항 및 콘덴서의 시정수를 이용하여 결정할수 있도록 함으로써 성능신뢰성 검사에 큰 효과를 준다.Therefore, in order to solve the conventional problem, the present invention allows the size and required position of a video signal to be sampled to be determined using a time constant of a resistor and a capacitor regardless of NTSC and PAL methods. It has a big effect on performance reliability test.
