Claims (2)
- 디지탈 데이타를 인가받아 래치시키는 래치(10)와, 그래치(10)로 부터 디지탈 신호로 인가받아 인가받아 내부 계산에 의해 출력데이타 기본주기 및 간격을 조절하는 보상용 데이타를 출력하는 마이콤(11)과, 전원(Vcc)을 인가받아 발진하는 발진부(14)와, 상기 마이콤(11)의 출력신호를 인가받아 상기 발진부(14)로 부터 클럭주파수가 인가될때 카운팅하는 카운터부(12)와, 그 카운터부(12)의 캐리 신호에 의해 로드신호(LD)를 분주하여 출력주파수 파형을 발생시키는 파형발생부(13)로 구성한 디지탈 데이타의 주파수 변환회로.
- 제1항에 있어서, 발진부(14)는 초기에 저항(R1), 콘덴서(C1), 다이오드(D1, D2)를 통해 카운터부(12)를 로드시키도록 구성되어 초기조건을 맞추어 주는 것을 특징으로 하는 디지탈 데이타의 주파수 변환회로.
