ABSTRACT:
A voltage controlled attenuator comprises a switching circuit operable for alternately coupling a capacitor to a source of input signal voltage and to a discharge circuit for first and second time intervals respectively, the duration of the second time interval being set in accordance with an applied control voltage. An output circuit includes apparatus for sampling the decayed input signal voltage developed by the capacitor following each of the second time intervals for developing an output signal comprising an attenuated representation of the input signal.
