ABSTRACT:
A signal transmission circuit includes a switched capacitor and a control circuit. The switched capacitor includes a capacitor and a plurality of switching means. The control circuit controls the frequency or level of a control signal to be applied to the switching means of the switched capacitor. By varying the frequency of the control signal with the control circuit, the equivalent resistance of the switched capacitor can be varied. By controlling the level of the control signal with the control circuit, at least one of the plurality of switching means is held in the "off" state thereof, to substantially inhibit the signal transmission of the switched capacitor.
