ABSTRACT:
Raster and particularly top and bottom pincushion distortion in a cathode ray tube system is corrected by applying a drive signal from the vertical output system of a television receiver to the vertical deflection winding of a yoke to effect activation of switching elements whereby correction signals of the proper phase and amplitude and derived from the horizontal scan system are applied to the vertical deflection winding such that a vertical deflection potential at a frequency fv is modulated by a horizontal deflection potential at a frequency fh and of the correct phase and magnitude.
