ABSTRACT:
A horizontal oscillator for a CRT device runs at a rate higher than the line rate, and has a wide lock-in range. The horizontal sync signal is delayed in an adjustable monostable circuit and coupled to the oscillator for allowing a centering adjustment of one full line. The oscillator output signal is coupled through a discharge circuit for rapid discharge of the subsequent circuit in the CRT device as desired.
