Abstract

1450924 Deflection coil driver circuits SIEMENS AG 10 Oct 1973 [23 Nov 1972] 47205/73 Heading H3T An amplifier feeding deflection coils, e.g. for character tracing, comprises a pre-amplifier 15 driving a power amplifier 16 connected to the coils 4, a second path 13 from the pre-amplifier to the coils to provide the high frequency components of the deflection coil drive and a coil 3 connected between the power amplifier and the coils 4 to prevent the high frequency components passing from the second path to the power amplifier. The need for the power amplifier to have a response at the higher frequencies is thus avoided. In Fig. 3, not shown, two such circuits are arranged to provide drive of opposite polarities.
