Fig. 23.8 (a) Required waveform of
magnetic deflection coil current. The
voltage waveform to overcome the coil
resistance is shown at (b), the voltage for
the coil inductance at (c), and the total
voltage at (d)
In general the deflection coils have both resistance and
inductance, so if a in Fig. 23.8 is the required deflection current the
part of the applied voltage needed for the coil resistance would have
the form shown at b, the part needed for the inductance at c, and the
total applied voltage at d. Quite a large amount of ingenuity has been
expended on means for economically generating acceptable
approximations to the ideal waveform ...
