Abstract
Description
Claims (1)
- 키조작부(5) 및 표시장치(14)가 연결된 마이콤(4)의 출력단에는 D/A변환기(3)와 증폭회로(2)를 통하여 발진회로(1)에 접속되고 이의 출력신호는 버퍼(9)를 거쳐 진폭조절부(10)와 비교기(6)에 각각 인가하되 비교기(6)의 출력 주파수는 F/V변환기(7) 및 비교기(8)를 경유하여 마이콤(4)으로 전송하며, 또한 진폭조절부(10)의 신호는 버퍼(11)를 거쳐 측정필터(12)에 인가하는 한편 상기 측정필터(12)의 출력은 버퍼(13)와 증폭회로(18) 및 피크검출기(17)를 통해 A/D변환기(16)로 인가하며 이의 출력 데이타는 래치회로(15)를 거쳐 마이콤(4)으로 전송하여서 된 것을 특징으로 하는 필터 특성 측정 장치.
