ABSTRACT:
A side pincushion correction circuit includes an impedance circuit coupled in series with the horizontal deflection coil. A switch coupled across at least a part of the impedance circuit is closed at a time during the retrace interval which is progressively advanced during a first portion of the horizontal retrace interval and progressively retarded during a second portion. Damping of the impedance circuit is provided by a second switch operated at a rate synchronous with the first. The second switch is coupled between a point of the impedance circuit and a voltage source.
