Abstract
Description
Claims (3)
- 기준입력신호보다 큰 값을 갖는 외란이 입력신호로 부터 작용했을 때 이를 제거한 신호(V1)를 출력하는 외란 제거 수단과;상기 외란 제거 수단에 연결되어 상기 외란 제거 수단으로 부터 출력된 신호(V1)로 부터 잡음이 제거된 출력신호를 얻기 위한 저역필터를 포함하는 것을 특징으로 하는 입력신호의 잡음 및 외란 제거회로.
- 제1항에 있어서, 상기 외란 제거 수단은 다이오드와 저항을 병렬로 연결 구성된 것을 특징으로 하는 입력신호의 잡음 및 외란 제거회로.
- 기준입력신호(REF+)(REF-)보다 큰 값을 갖는 외란이 Vin 으로 부터 작용했을 때로서 Vin>0 일 경우, 입력신호(Vin)로 부터 외란이 제거된 신호인 V1은;V1=R1*Vin/(R4+R1)+0.7V-R1*R7*VCC/(R4+R1)/(R7+R6)으로 제거하고,Vin<0 일 경우, 입력신호(Vin)로 부터 외란이 제거된 신호인 V1은;V1=R2*Vin/(R4+R2)-0.7V-R2*R8*VCC/(R4+R2)/(R8+R9)로 그 제거가 이루어지도록 함을 특징으로 하는 입력신호의 잡음 및 외란 제거방법.
