Abstract
Description
Claims (1)
- 소인주기발생부와 주파수변조부가 무안정멀티바이브레이터로 구성되는 경보기용 소인신호발생기에 있어서;소인주기발진부 무안정멀티바이브레이터의 두 베이스저항과 톱니파발생부의 충전저항을 전류제한저항과 제너다이오드로 구성된 정전압부에 접속하고, 주파수변조부 무안정멀티바이브레이터의 두 베이스저항 중 스피커드라이버 트랜지스터의 턴온시간을 결정하는 트랜지스터의 베이스저항을 전원측에 접속함으로서 전원전압의 변화에 따른 소인주기와 변조주파수 및 출력의 변화를 감소시키는 것을 특징으로 하는 경보기용 소인신호발생기.
