Claims (1)

라디오 방송수신용 튜너와 녹음회로를 구비한 음향기기의 비트음 제거회로에 있어서, 녹음스위치의 동작시 방송신호가 녹음헤드에 유입되는 것을 소정의 시간동안 차단시키기 위한 뮤팅부와, 라디오의 오디오 출력단에서 출력되는 비트음 신호를 검출하고, 이를 정류하여 구형파로 변환시키기 위한 구형파 발생부와, 상기의 구형파를 입력으로 하여 녹음스위치를 눌렀을 경우 소정의 제어신호를 발생시키기 위한 제어신호 발생부 및 상기의 제어신호에 의해 동작하여 녹음헤드에 인가되는 비트음을 자동으로 제거하기 위한 비트음 제거부로 구성시켜서 됨을 특징으로 하는 비트신호 자동제거회로.In the beat sound removing circuit of an acoustic apparatus provided with a tuner for receiving a radio broadcast and a recording circuit, a muting unit for blocking a broadcast signal from flowing into the recording head during a predetermined time when the recording switch is operated, and an audio output terminal of the radio. A square wave generator for detecting a beat sound signal outputted from the rectifier, rectifying it, and converting it into a square wave, and a control signal generator for generating a predetermined control signal when the recording switch is pressed using the square wave as an input; And a beat sound removing unit for automatically removing the beat sound applied to the recording head by operating by a control signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
