Horizontal deflection waveform correction circuit |
摘要 |
A deflection apparatus comprises a deflection amplifier coupled to a deflection waveform modulation circuit such as a diode modulator. An East-West modulation signal is generated by a digital to analog convertor in accordance with a reference potential coupled thereto. The modulation signal has a DC component for width control, and is coupled to an input of a comparator. The reference potential is also coupled to an input of the comparator to establish a reference bias therefor. The comparator has an output coupled to the deflection waveform modulation circuit to provide the East-West modulation.
