Claims
- 1. A delay-compensating dynamic focus amplifier, comprising:
- a delay-compensation circuit comprising first and second multivibrators for receiving a horizontal flyback signal and for 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 focus waveform generator.
- 2. The delay-compensating dynamic focus amplifier as defined in claim 1, wherein the focus waveform generator comprises:
- a push-pull output stage for varying its output voltage under the control of the controller; and
- a field effect transistor for amplifying the output waveform received from the delay-compensation circuit.
