Raster distortion correction circuit.

摘要

A video display having deflection correction comprising a cathode ray tube (100) with a deflection coil (RH) mounted on the cathode ray tube (100) for generation of a raster having horizontal line length variations which describe a generally sinusoidally shaped raster edge. A deflection amplifier (70) is coupled to the deflection coil (100) for generating a deflection current therein. A modulator (65) is coupled to the deflection coil (RH) for generating a corrective current therein responsive to a corrective signal (Hc). A corrective signal generator (50) for generating said corrective signal (Hc) having a generally sinusoidal shape is coupled to the modulator (65) for raster edge correction. <IMAGE>
