Description

자기 재생장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도 내지 제4도는 본 발명의 자기 재생장치에 사용되는 리미터 회로의 제1실시예 내지 제4실시예의 구성도.

Claims (1)

  1. 자기 기록된 FM 신호를 복조하여 재생 휘도신호를 얻는 복조 회로의 앞단에 부귀환 회로를 설치한 자기 재생 장치로서, 상기 부귀환 회로는, 상기 FM신호 또는 상기 FM신호에 의한 신호가 공급되는 비반전 입력 단자를 구비한 증폭회로와, 이 증폭 회로로부터의 출력 신호의 진폭 제한을 행하는 리미터 회로와, 이리미터 회로로부터의 진폭 제한 신호를 소정시간 지연하여 얻은 지연 신호를 상기 증폭 회로의 반전 입력단자에 공급하는 지연 회로로 형성되며, 상기 FM 신호에 대해, 상기 지연 신호가 상기 FM 신호의 캐리어 주파수 대역에 있어서 90°의 위상 지연을 가지고 부귀환 하므로서, 상기 리미터 회로로 부터의 상기 진폭 제한 신호를 상기 복조 회로에 공급하도록 구성하는 것을 특징으로 하는 자기 재생장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
