Abstract

PURPOSE: To secure extraction of only the common component out of two signals possessing different components by providing plural sets of the composite circuit which functions as the AND circuit to the signals sent from the reference voltage to one direction and then as the OR circuit to the signals sent to the other direction each.
CONSTITUTION: Signal A sent from input terminal 1 is applied to 1st and 2nd 1st- type compounding circuits 4 and 5; and signal B from input terminal B is applied to 2nd and 3rd 1st-type compounding circuits 5 and 6 respectively. Then output CD, EF and GH of the AND and OR of these compounding circuits 4∼6 are applied to 2nd-type compounding circuit 7. And the output I of circuit 7 is amplified when necessary through amplifier circuit 8, and output I' is applied to the input of circuits 4∼6. Thus circuts 4∼6 are made to function as the AND circuit to the input from the reference voltage to one direction as well as the OR circuit to the signal toward the other direction respectively. Then only the common component is extracted between signals A and B to the output of circuit 8.
