Abstract
본 발명은 광 신호 생성 회로, 제어 회로, 파형 성형 회로, 및 출력 회로를 포함한다. 광 신호 생성 회로는 펄스들을 포함하는 제 1 광 신호를 생성한다. 제어 회로는 펄스들 중 크기를 감쇄시킬 것으로 결정된 제 1 펄스를 지시하는 제어 신호를 생성한다. 파형 성형 회로는 제어 신호 및 제 1 광 신호에 기초하여, 제 1 펄스의 크기를 감쇄시키고, 감쇄된 크기를 갖는 제 1 펄스 및 제 1 광 신호에 포함된 펄스들에 대응하는 펄스들을 포함하는 제 2 광 신호를 생성한다. 출력 회로는 제 2 광 신호에 기초하여, 제 2 광 신호에 포함되는 펄스들의 주파수들 사이의 차이들에 대응하는 대역들의 전기 신호를 출력한다. 제 1 펄스의 크기가 감쇄함에 따라, 전기 신호의 대역들 중 제 1 펄스에 대응하는 대역이 조절된다.
