Abstract
An electron beam deflection control system includes a first signal generation circuit which generates a triangular signal varying at a comparatively low speed, a second signal generation circuit which generates a stepped signal varying at a comparatively high speed, and a switching arrangement to change over the first and second signal generation circuits and to drive one of them, whereby the signal from the generation circuit selected by the switching arrangement is used as a deflection signal for an electron beam.
