Abstract
본 발명은 컴팩트디스크나 카셋트등의 오디오셋트에서 뮤팅을 걸때 발생하는 팝 노이즈를 제거하는 노이즈 제거용 뮤팅회로에 관한 것이다.The present invention relates to a noise removing muting circuit for removing pop noise generated when muting is performed on an audio set such as a compact disc or a cassette.
뮤팅스위치를 네가티브 피드백회로의 피드백 저항과 병렬로 연결하여 입력시그널 자체를 감쇄시켜 뮤팅시의 노이즈를 제거하므로 종래 뮤팅회로에 있어서 캐패시터 전위 방전시 발생하는 팝 노이즈 문제를 해결함과 동시에 개별소자를 이용하지 않고 집적화할수 있어 매우 유용하다.By connecting the muting switch in parallel with the feedback resistor of the negative feedback circuit, the input signal itself is attenuated to remove the noise during muting. Therefore, the conventional muting circuit solves the pop noise problem caused by the capacitor potential discharge. Very useful because it can be integrated without.
