Title:
VOICE POWER SUPPLY PICKUP CIRCUIT FOR TELEVISION RECEIVER
Document Type and Number:
Japanese Patent JPS5728478
Kind Code:
A
Abstract:
PURPOSE: To avoid distortion on screen, by cancelling the changing part caused on a horizontal deflection current and a flyback pulse voltage with voice output.
CONSTITUTION: A current flowing to a resistor 18 with an voice output is changed and the collector voltage of a transistor (TR) 20 is changed correspondingly. The collector voltage of the TR20 is applied to the base of a TR25 via a low pass filter consisting of resistors 22, 23 and a capacitor 24, and the reactance of a saturable reactor 17 is controlled and the deflection current is controlled. That is, when a voice output is increased, the reactance of the reactor 17 is decreased and the deflection current is increased.
