ABSTRACT:
A CRT deflection circuit for use in a flying spot telecine scanner comprises a linear amplifier with a resonant flyback circuit and a flyback shift circuit comprising an inductive DC path carrying a DC offset current and a capacitor carrying the raster scan AC current to the flyback circuit. Since the DC offset current is not applied to the flyback circuit, the circuit can fly-back to non symmetrical beam positions, so that the entire scan can be displaced by a shift applied to the input of the amplifier.
