Claims (1)

  1. 영상 신호 입력 단자에 공급되는 입력 영상 신호를 그의 방송 색 신호 대역 및 그의 저역측의 전대역에 걸쳐 1수평주기 또는 2수평주기 지연시키는 회로를 가지며, 상기 영상 신호 입력 단자와 제1출력단자간에 상기 지연회로를 포함하여 감산형 빗형 필터를 구성함과 함께 상기 영상 신호 입력 단자와 제2출력 단자간에 상기 회로를 포함하여 가산형 빗형 필터를 구성하느 신호 분리부와,
    상기 제1출력 단자에 접속되어, 상기 반송 색 신호 대역의 저역측에서의 소정 대역을 증강함과 함께,
    상기 반송 색신호 대역을 감쇠시키는 대역 증강 감쇠 회로와,
    상기 제2출력 단자에서 얻어진 신호에 대하여 상기 대역 증강 감쇠 회로의 출력 신호를 가산하는 가산회로를 구비하는 것을 특징으로 하는 영상 신호 분리장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
