发明名称 SCREEN DISTORTION CORRECTING CIRCUIT
摘要 PURPOSE:To realize a longitudinal line winding correction inexpensively by utilizing current flowing from a+B power source by the voltage according to the brightness of several volts. CONSTITUTION:This circuit is a horizontal output circuit having a diode modulator constitution and is a distortion correction circuit where the voltage of a modulation capacitor 12 is modulated by an NPN transistor 21 and this transistor is driven by the difference signal of the negatively fed back voltage from the modulation capacitor 12 and an input signal. A brightness signal is newly superposed on the polarity which reduces the brightness components from the negatively fed back voltage from the modulation capacitor 12 by a resistor 23 and a capacitor 24.
