Abstract
A delay-compensating dynamic focus amplifier includes a delay compensation circuit including two one-shot multivibrators for receiving a horizontal flyback signal and generating a sawtooth wave to compensate for a delay by adjusting a duty cycle, a focus waveform generator for receiving a delay-compensation output signal from the delay-compensation circuit and for generating a horizontal parabolic waveform, an amplifier for receiving the horizontal parabolic waveform from the focus waveform generator and for amplifying it depending on a regulated gain so as to provide a predetermined output current, and a controller for providing a control signal to the delay-compensation circuit and the waveform generator.
