发明名称 CRT scan system dynamic focus circuit.
摘要 <p>A method and apparatus for generating a dynamic focus correction voltage signal for a cathode ray tube which comprises the steps of: generating horizontal and vertical scan counter signals, and inputting the counter signals to a dynamic output voltage generating means which produces an output voltage that is proportional to the distance the scan is from the center of the image on the CRT in both the vertical and the horizontal directions. &lt;IMAGE&gt;</p>
