Abstract: Stroke display system for the display of images comprising a low-pass filter (50) in the positional signal path, a time-discrete positional signal, and precompensation of this time-discrete signal for phase and amplitude errors of the overall positional control circuitry. As a consequence, the uncompensatable vector nonlinearities of the prior art vector stroke are obviated, the useable system bandwidth or stroke per unit time is extended beyond the prior art to the maximum driveable frequency, and in many text and graphics applications fewer strokes are needed to produce the desired image.
