TV시스템의 신호 처리용 ICSignal Processing ICs for TV Systems

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제3도는 본 발명에 따른 TV시스템의 신호 처리용 IC의 블럭 다이어그램.3 is a block diagram of an IC for signal processing of a TV system according to the present invention.

Claims (1)

TV 시스템의 신호 처리용 IC를 구성함에 있어서, 사운드 IF신호를 디텍션 하기위한 입력이 하나의 핀으로 구성되고 파일럿 신호만을 패스하기 위한 밴드패스 필터(BPF)가 내부에 내장되며 AM디텍션을 하기 위해 외부에 콘덴서(C)가 연결되어 내부 바이어스를 잡아주고 디텍터 출력에 저항과 콘덴서로서 로우패스 필터를 형성하여 레벨을 변화시킬수 있으며 모드 셀렉션 입력에 의해 L-출력 및 R-출력이 모노일 경우에는 모노로, 스테레오일경우는 스테레오와 모노로, 밸링걸일 경우는 모노 또는 메인과 서브로 구동되며, 모노 방송일 경우 수우도 스위치(P/S)로서 조작하여 수우도 스테레오를 들을수 있도록 구성한 것을 특징으로 하는 TV시스템의 신호 처리용 IC.In constructing the signal processing IC of the TV system, the input for detecting the sound IF signal is composed of one pin, and a band pass filter (BPF) for passing only the pilot signal is internally built and the external for AM detection. The capacitor (C) is connected to hold the internal bias, and the level can be changed by forming a low pass filter as a resistor and a capacitor at the detector output.If the L-output and R-output are mono by the mode selection input, In case of stereo, it is driven by stereo and mono, and in the case of a ball girl, it is driven by mono or main and sub. IC for processing. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
