스테레오 파일로트 신호를 검출하는 스테레오 모듀울(5)의 출력으로 모우드를 절환시키는 마이콤(10)에 있어서, 상기 스테레오 모듀울(5)에서 스테레오 파일로트 신로를 검출한 출력이 인가되면 현재 모우드를 체크하고 지연시키는 과정을 수행시킨 후 일정 시간동안 지속적으로 인가될때 스테레오 모우드로 절환시키는 과정이 수행되게 하고 스테레오 파일로트 검출신호가 인가되지 않으면 현재 모우드를 유지시키도록 하는 스테레오 모우드 절환시 오동작 방지 방법.In the microcomputer 10 for switching the mode to the output of the stereo modulus 5 for detecting a stereo pilot signal, the current mode is checked when an output for detecting a stereo pilot path is applied from the stereo modul 5. And switching to the stereo mode when the signal is continuously applied for a predetermined time after performing the delaying process, and maintaining the current mode when the stereo pilot detection signal is not applied. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
