  • Regulation of the scan width of a raster scanned CRT deflection system
    Patent number: 4414494
    Abstract: The input voltage to the deflection system of a raster scanned CRT is made variable and is controlled by a feedback network in such a way that the width of the raster remains constant regardless of scanning frequency variations.
    Type: Grant
