ABSTRACT:
A horizontal deflection generator provides scanning current in a deflection winding and a pincushion modulating circuit is coupled to the deflection winding for modulating the horizontal scanning current. A vertical deflection generator and the horizontal deflection generator are coupled by means to the modulating circuit for providing vertical rate signals and nonlinear horizontal rate signals to the modulating circuit for providing a vertical rate distortion correction signal component modulated by the nonlinear horizontal rate signals for reducing the side pincushion distortion.
