Abstract: A high-speed digital deflection switch system incorporating a digital-to-analog conversion circuit comprising a plurality of resistors in a ladder network which are switched into and out of the circuit by digital input signals for providing current changes through a magnetic deflection coil. This circuitry is accompanied by linearizing capacitors to produce a more constant deflection rate and further includes a circuit for changing the character size from large to small letters.
