Claims (2)

입력신호를 반파 정류한 후 피크치를 보지한 정류보지 회로와, 그 정류보지 회로내의 피크치 보지수단에 대하여 설치된 그 입력신호 레벨이 그 보지수단의 보지전압보다도 일정레벨치 이하로 된 때 그 보지수단의 보지전압을 감소시키는 스위칭 수단과, 그 피크치 보지 수단의 보지 전압과 입력전압을 각각 레벨비교하는 레벨 비교기로 이루어진 레벨 검출회로부를 그 입력신호의 플러스(正), 마이너스(負)의 반파 각각에 대하여 설치하고, 그 각각에 대하여 설치한 레벨 검출회로부의 각 레벨 비교기의 출력신호를 각각게이드 회로를 통하여 그 입력신호의 진폭정보를 논리 출력하게 구성한 것을 특징으로 하는 신호검출장치.The rectifying holding circuit holding the peak value after half-wave rectifying the input signal, and the input signal level provided for the peak holding means in the rectifying holding circuit is lower than the holding voltage of the holding means. A level detecting circuit section comprising switching means for reducing the holding voltage and a level comparator for level comparison of the holding voltage and the input voltage of the peak value holding means, respectively, for each of the positive and negative half waves of the input signal. And the output signal of each level comparator of the level detection circuit section provided for each of them is configured to logically output the amplitude information of the input signal through a gaze circuit. 제1항에 있어서, 입력신호가 2치 부호신호가 기록되어 있는 자기 기록매체에서 재생된 3치 부호신호인 것을 특징으로 하는 검출장치.The detection apparatus according to claim 1, wherein the input signal is a three-value code signal reproduced from a magnetic recording medium on which a binary code signal is recorded. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
