ABSTRACT:
A device for displaying variable quantities on the viewing screen of a cathode-ray tube by means of deflection coils which are energized by a number of deflection amplifiers coupled to different supply voltages, the deflection amplifier with the lowest supply voltage serving for signal components with the lowest frequencies and that with the highest supply voltage for the signal components with the highest frequencies. This results in a substantial reduction in power consumption.
