Abstract
A cathode ray dual mode electromagnetic beam deflection amplifier system for providing current for driving a deflection coil, and means for switching between linear and resonant non-linear operational modes. In the linear mode, the deflection coil current is controlled to closely follow an applied input deflection sweep voltage and operates as a push-pull amplifier. In the non-linear resonant mode, one-half the output stage is abruptly decoupled from the deflection coil such that energy stored in the deflection coil is discharged into a series capacitor, the subsequent resonant pulse being returned through the non-decoupled half of the output stage to a power supply.
