Abstract

본 발명은 다채널 신호 상에서 발생하는 상호변조에 의한 왜곡신호를 측정하는데 발생되는 기존의 에러발생 원인을 제거하여 측정의 정확도와 객관성을 높이기 위하여, 왜곡신호 측정대상과 수신기 및 스펙트럼 분석기 사이에, 대역통과필터와, 대역소거필터와, 정합기를 포함시켜 구현한 왜곡신호 추출회로에 관한 기술이다.The present invention provides a band between a distortion signal measuring object and a receiver and a spectrum analyzer in order to remove an existing cause of error occurring in measuring a distortion signal due to intermodulation occurring on a multi-channel signal, and to increase the accuracy and objectivity of the measurement. The present invention relates to a distortion signal extraction circuit implemented by including a pass filter, a band cancellation filter, and a matcher.
