Abstract
Description
Claims (1)
- 스테레오 ID신호검출용 PLL회로와 이중음성 ID신호 검출용 PLL회로의 출력을 비교하는 비교부(11)와, 전류미러 사이에 접속되어 상기 비교부의 출력에 따라 스위칭되고 음성다중 신호조절부 및 매트릭스부를 제어하는 출력을 내보내는 출력제어부(12)와, 상기 출력제어부로부터 일정 레벨이 출력될 때 동작하여 제1, 2전류미러를 동작하게 하는 제1, 2전류소스(13)(14)와, 상기 제1, 2전류소스의 동작에 따라 증가된 일정크기의 전류를 계속적으로 출력시키는 제1, 2전류미러(15)(16)를 구비하여서 이루어짐을 특징으로 하는 음성다중 ID신호검출 및 제어회로.
