Claims (5)
- 신호 처리 방법에 있어서, 입력 신호를 비율 회로(16)에 인가시키는 단계와, 입력 신호의 최소값과 사실상 동일한 값을 갖는 기준 신호를 발생시키는 단계와; 입력 신호와 기준 신호간의 차이에 비례하는 비율 신호를 발생시키는 단계와, 기준 신호보다 큰 오프셋 신호를 발생시키는 단계와, 입력 신호를 수신하기 위한 비교기를 사용하면서 오프셋 신호와 비율 신호중 더 큰 신호로서 비교기(26)를 바이어싱시키는 단계로 구성되어 있는 신호 처리 방법.
- 제1항에 있어서, 비교기(26)를 바이어싱시키는 단계는 오프셋 신호와 비율 신호중 더 큰 신호를 비교기(26)를 바이어싱시키기 위한 저장 소자(28)에 인가시키는 단계를 포함하고 있는 방법.
- 제1항에 있어서, 비율 회로(16)에 입력 신호를 인가시키는 단계는 상기 입력 신호를 만들기 위해 수신된 신호를 증폭시키는 단계를 포함하고 있는 방법.
- 신호 처리 방법에 있어서, 입력 신호와 오프셋 신호중에서 더 큰 신호를 선택함으로써 바이어스신호를 발생시키는 단계와 입력 신호를 바이어스 신호와 비교하는 단계로 구성되어 있으며, 상기 오프셋 신호는 입력 신호의 최소값 보사 큰 것이 특징인 신호 처리 방법.
- 제4항에 있어서, 바이어스 신호를 발생시키는 단계는 입력 신호와 입력 신호의 최소값과의 차이를 이용하여 입력 신호 한 부분을 형성하는 단계를 포함하고 있는 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
