Abstract

본 발명은 하이-파이에서 초기 트랙킹 기간중 발생하는 노이즈를 제거하기에 적당하도록 한 브이 씨 알의 하이-파이 노이즈 제거 장치에 관한 것으로 기존에는 엔벨로프 파형의 양(레벨)에 의해 하이-파이를 택일하게 되어 있으므로 엔벨로프 스윙기간동안은 FM파형의 레벨 변화를 가져와 노이즈를 수반하게 되는 문제가 있어 본 발명에서는 종래의 구성에 하이-파이 처리부(5)에 접속도어 오토 트랙킹 기간중 하이-파이 뮤트 신호를 출력시키도록 제어하는 마이컴(10), 하이-파이처리부(5)의 출력측과 마이컴의 출력측 사이에 접속되어 오토 트랙킹 기간중 하이-파이 출력을 뮤트시키고, 노멀 출력을 내보내도록 스위칭하는 스위칭 소자(11)를 추가로 구비하여 노이즈를 제거하도록 한 것이다.The present invention relates to a V-seal hi-fi noise canceller that is suitable for removing noise generated during an initial tracking period in hi-fi. In the present invention, there is a problem in that the level of the FM waveform is changed during the envelope swing period, thereby accompanied by noise. In the present invention, the hi-fi mute signal is connected to the hi-fi processing unit 5 in the conventional configuration. A switching element 11 connected between the microcomputer 10 controlling the output and the output side of the hi-fi processing unit 5 and the output side of the microcomputer to mute the hi-fi output during the auto tracking period, and to switch to output a normal output. ) To further remove noise.
