SCANNING SPEED MODULATION DEVICE AND TELEVISION RECEIVER PROVIDED WITH SAME

摘要

PROBLEM TO BE SOLVED: To provide a scanning speed modulation device capable of obtaining a television receiver having fine display performance by solving a problem such as ringing generated by electrostatic coupling between a deflecting yoke and a scanning speed modulation coil. SOLUTION: A scanning speed modulation signal of positive polarity is applied from one terminal of the scanning speed modulation coil 49, a scanning speed modulation signal of negative polarity is applied from the other terminal of the coil 49 and the potential integration value of the coil 49 is set up to be zero in each moment.
