ABSTRACT:
A system for synchronous alignment of cathode ray tube (CRT) rasters by application of time variable rotation driver signals to the CRT rotation coil during trace of the raster. The system may be implemented by either digital or analog means of measuring and storing cathode ray tube raster distortion data as rotational correction factor data. The rotational correction factor data is used by device circuitry to generate and apply the required time variable rotation driver signals, to the CRT rotation coil, to effect the desired CRT raster alignment.
