Abstract
A Raster and Stroke Writing Deflection Amplifier Arrangement for a cathode ray tube (CRT) is disclosed which uses a conventional vertical oscillator and vertical deflection amplifier and a conventional horizontal oscillator and synchronous horizontal deflection amplifier, both driving deflection coils for providing vertical and low power horizontal scan operation for raster scan writing of data, and a flyback transformer and rectifier for providing the high D.C. voltage required by the CRT anode by rectification of high surge voltages created during horizontal retrace periods. During each vertical retrace period a switch connects the synchronous horizontal deflection amplifier to a dummy yoke at a zero crossing of the horizontal deflection signal for uninterrupted operation, connects a source of horizontal stroke writing signals amplified by a linear amplifier to the deflection coil, and also connects a source of vertical stroke writing signals to the vertical deflection amplifier to drive the deflection coil to accomplish stroke writing of information during each vertical retrace period.
