Abstract
Description
Claims (1)
- 입력신호를 각각 제1 및 제2 기준전압(Vhigh, Vlow)과 비교하여 상기 입력신호가 상기 제1 및 제2기준전압(Vhigh, Vlow)보다 클 경우 소정의 펄스를 출력하는 제1및 제2비교기(OP1, OP2)와, 상기 제1 및 제2비교기(OP1, OP2)로 부터 각각 입력한 신호의 상승에지에서 소정 저항과 콘덴서의 시정수(R1과 C1 혹은 R2과 C2)를 갖는 펄스를 발생시키는 제1 및 제2단안정 멀티바이브레이터(MMV1, MMV2)와, 상기 제1 및 제2단안정 멀티바이브레이터(MMV1, MMV2)로 부터 제3 및 제4출력신호(S3, S4)를 입력하여 소정상태의 제어신호(Q)를 출력하는 쌍안정 래치회로(100)와, 상기 제어신호(Q)의 상태에 따라 상기 제2비교기(OP2)로 부터 제2출력신호(S2)를 입력하여 원하는 기준입력(Vhigh, Vlow) 사이의 크기를 갖는 신호 발생 시점에서 소정저항과 콘덴서(R5, C3)의 시정수를 갖는 검출펄스(S5)를 출력하는 제3단안정 멀티바이브레이터(MMV3)로 구성되어 특정 범위내의 신호 혹은 잡음을 검출함을 특징으로 하는 신호 및 잡음 검출회로.
