Claims (1)

마이크(1)을 통하여 인가되는 초기상태 신호(Xi)를 일정시간(T) 지연시켜 지연상태 신호(Xi-T)가 출력하도록 구성하고 초기 상태신호와 지연상태 신호를 비교하여 피드백 회로(16)를 구성한 후 출력측을 뮤트시키는 마이크의 하울링 방지 방식.The delayed state signal Xi-T is outputted by delaying the initial state signal Xi applied through the microphone 1 by a predetermined time T, and comparing the initial state signal and the delayed state signal to the feedback circuit 16. How to prevent howling of the microphone to mute the output side after configuring. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
