Abstract
Description
Claims (1)
- 비데오 신호의 입력상태에 따른 제어신호(IDENT)가 저항(R3)의 일측단자에 접속되고 상기 저항(R3)의 타측단자는 전원전압(Vcc)을 분압하여 트랜지스터(Q1)의 베이스에 입력되는 저항(R1, R2)의 공통 접속점에 연결되며 상기 트랜지스터(Q1)의 에미터는 저항(R5)에 의해 전원(Vcc)에 접속됨과 아울러 마이콤(1)의 A/V 출력단자(A/V OUT)에 공통 접속되고 상기 트랜지스터(Q1)의 콜렉터는 저항(R4)을 통해 상기 마이콤(1)의 브라이트 제어단자(V1)와 함께 공통접속되어 외부의 브라이트 제어회로에 제어신호(Vout)를 출력하도록 구성한 것을 특징으로 하는 무신호시 화면 블랭킹 방지회로.
