摘要: A method and apparatus used to step correct the position of raster lines in a sinusoidal or zig-zag deflection system. By combining magnetic flux generated with rotation 'twister' coil vertical coil, scan can be uniformly spaced separated nearly their ends. Accordingly, twister is adjusted going left right direction then reversed polarity readjusted while returning from left. It this controlled that combines linear straighten each line produce an aligned raster.
