Abstract
A circuit for driving a deflection coil comprising a capacitor (3) in series with the coil (2), a circuit (1) which drives a saw-tooth waveform current through the coil and capacitor, and a switchable resonant circuit (5, 6, 7, 8, 9) which generates across the capacitor a saw-tooth waveform voltage equal and opposite to the voltage drop attributable to a resistive component (4) of the capacitor/coil series circuit, thereby to effect loss correction.
