Abstract
A circuit for controlling the amplitude of video signals includes a control circuit which contains a first capacitor. For each image pulse, a charge which corresponds to the amplitude of the generated video signal during a prior frame cycle is stored in the first capacitor. During the frame flyback pulse, this charge is transferred to a second capacitor by means of a switch. The second capacitor's voltage serves as a control voltage for the video signal. After the charge is transferred to the second capacitor, the first capacitor is discharged.
