Claims (1)

전원 온·오프 또는 채널절환시 마이콤(1)이 그의 제어신호입력단자(CS1)로 입력되는 동기신호(SS)를 카운트하기 위해 카운트수(K1)를 설정하고, 입력되는 동기신호(SS)를 카운트하여 설정된 카운트수(K1)에서 감산한후, 그 결과가 제로가 되었는지 판별하여 방송신호의 유무를 판별하고, 그 방송신호의 유무에 따라 마이콤(4)이 그의 제어신호출력단자(CS2)로 저전위 및 고전위를 출력하여 음성증폭부(5)의 출력신호를 출력 및 뮤팅시키게 제어함을 특징으로 하는 무신호시 음성소거방법.When the power supply is turned on or off or the channel is switched, the microcomputer 1 sets the count number K 1 to count the synchronization signal SS input to its control signal input terminal CS 1 , and inputs the synchronization signal SS. ) Is subtracted from the set count number K 1 , and the result is zero to determine whether or not there is a broadcast signal. CS 2 ) outputting low and high potentials to output and mute the output signal of the voice amplifier 5. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
