Abstract
Video display distortion in a television receiver introduced by input voltage excursions is compensated for by a voltage regulation circuit which tracks the changing input line voltage while automatically switching to an active filter mode once the line voltage has decreased to a predetermined level. This permits the removal of AC transients from the fluctuating input signal and avoids display degradation resulting therefrom.
