ABSTRACT:
An integrating circuit comprises an integrating amplifier having an inverting input for receiving a signal to be integrated, and a feedback capacitor connected between the output of the amplifier and its inverting input. The output of the integrating amplifier is connected one input of a second amplifier having another input connected to zero potential. The output of the second amplifier is connected to a diode switching arrangement which is actuated between a conductive state in which a d.c. connection is established between the output of the second amplifier and the inverting input of the integrating amplifier and the feedback capacitor is forcibly discharged and a non-conductive state in which the d.c. connection is interrupted and the output of the second amplifier is connected to zero potential so as to enable the integrating amplifier to integrate the signal received by its inverting input.
