Claims (3)
- 기준주파수를 발진하는 기준주파수발진부(1)와, 그 기준주파수발진부(1)에서 출력되는 기준주파수를 외부에서 공급되는 비교입력펄스에 동기시켜 입력받는 기준주파수제어부(5)와, 상기 기준주파수제어부(5)의 출력신호를 카운트하는 카운터(7)와, 기준펄스폭 설정데이타를 저장하는 레지스터(8)와, 상기 카운터(7)의 카운트신호를 상기 레지스터(8)의 기준펄스폭 설정데이타와 비교하여 상기 기준주파수제어부(5)의 리세트를 제어하는 비교기(9)와, 상기 기준주파수제어부(5)의 출력신호에 의해 세트제어를 받고 상기 비교기(9)의 출력신호에 의해 리세트제어를 받아 기준펄스를 발생하는 에스알플립플롭(6)과, 상기 에스알플립플롭(6)에서 출력되는 기준펄스와 상기 비교입력펄스를 비교하여 그 펄스폭 차이를 출력하는 위상검출부(3)로 구성하여 된 것을 특징으로 하는 기준펄스 발생회로.
- 제1항에 있어서, 기준주파수제어부(5)는 비교입력펄스를 클럭신호로 인가받고 비교기(9)의 출력신호에 의해 리세트제어를 받는 디플립플롭(D-F/F)과, 그 디플립플롭(D-F/F)의 출력신호와 기준주파수발진부(1)에서 출력되는 기준주파수를 앤드조합하는 앤드게이트(AND1)로 구성하여 된 것을 특징으로 하는 기준펄스 발생회로.
- 제1항에 있어서, 카운터(7)는 위상검출부(3)에서 펄스폭 검출시에 발생하는 검출완료신호에 의해 클리어되게 구성된 것을 특징으로 하는 기준펄스 발생회로.
