ABSTRACT:
The output of an amplification assembly is coupled with the input of an integrating circuit by means of a first controlled switch. The output of the integrating circuit is coupled with the input of an intermediate stage and subtracted from the amplifier input signal during quiescence of the amplifier. The signal delivered by the amplification assembly is also applied to the input of a logical detection circuit which opens the first switch and closes a second switch discharging the integrating circuit in response to any rapid-variation pulse applied to its input, thus disabling the integration-subtraction operation, but closes the first switch and opens the second to enable integration and subtraction when the signal applied to the input of the detection circuit is steady or is subject only to slow variations.
