Abstract
A video display having deflection correction comprising a cathode ray tube with a deflection coil mounted on the cathode ray tube for generation of a raster having horizontal line length variations which describe a generally sinusoidally shaped raster edge. A deflection amplifier is coupled to the deflection coil for generating a deflection current therein. A modulator is coupled to the deflection coil for generating a corrective current therein responsive to a corrective signal. A corrective signal generator for generating said corrective signal having a generally sinusoidal shape is coupled to the modulator for raster edge correction.
