ABSTRACT:
A line deflection current generator and a diode modulator for influencing the amplitude of the generated deflection current but without influencing the d.c. voltages which are also generated by the generator, a controllable switching device, for example, the series arrangement of a coil and a thyristor being included in parallel with one of the diodes of the diode modulator and with the opposite direction of conduction. This controllable switching device can also serve as control element for the amplitude modulation.
