Abstract
A scan velocity modulation (SVM) coil arrangement for a cathode ray tube has SVM coils arranged on a rear portion of the main horizontal deflection coils. The main horizontal coils are of the saddle type and have flat end turns at the rear of the deflection coil, lying along the surface of the picture tube. The SVM coil is placed over the flat rear end turns forward of the static convergence magnets and forward of ferromagnetic materials associated with the electron gun. The sensitivity of the SVM coil is increased to the point that the coil can be efficiently driven in a progressively scanned raster display, at twice the horizontal rate of an interleaved raster display.
