Abstract

직접 디지탈 합성기 및 디지탈 주파수 분할기를 사용하는 디지탈 파형 합성기가 제공된다. 직접 디지탈 합성기는 디지탈 합성된 입력 주파수 신호를 제공한다. 상향 변환기 및 주파수 분할기 회로는 분할된 합성 주파수 신호를 제공하기 위해 합성 입력 주파수 신호를 상향 변환하여 분할한다. 출력 상향 변환기 회로는 상향 변환된 출력 주파수 신호를 제공하기 위해 상향 변환기 및 분할기 회로에 결합된다. 기준 주파수 발생기는 이에 클럭 및 주파수 기준 신호를 제공하기 위해 직접 디지탈 합성기, 상향 변환기 및 분할기 회로 및 출력 상향 변환기에 결합된다. 파형 발생기는 원하는 파형을 명령하기 위해 직접 디지탈 합성기에 결합된다. 주파수 분할기는 직접 디지탈 합성기의 고유하게 빈약한 위사 신호성능을 개선하는데 사용된다. 디지탈파형 합성기는 빠른 스위칭의 신축성 있고 정밀하게 정해지는 주파수 출력 신호를 제공한다. 디지탈 파형 합성기는 고 스펙트럼 순도 및 주파수 정밀성을 요구하나 비교적 좁은 신호 대역폭을 요구하는 임의의 신호 발생기에 사용될 수 있다.
