PURPOSE:To prevent screen disturbing noise from being produced due to distortion and the transient characteristic of a collector current and a damper diode current, etc., by providing the horizontal deflection circuit having a diode modulator form. CONSTITUTION:A parallel circuit composed of an inductor 20 and a resistor 21 is connected in series with the collector of a horizontal output transistor(TR) 2, a parallel circuit composed of an inductor 22, a resistor 23 and a high speed diode 24 is connected between a connecting point A between 1st and 2nd damper diodes 3, 4 and a connecting point B among 1st and 2nd resonance capacitors 5, 6, a 1st scanning capacitor 8 and a modulation coil 9, and a 3rd damper diode 25 is connected in parallel with the 2nd resonance capacitor 6. By such constitution, the diode modulator type horizontal deflection circuit corresponding to multi-frequency is obtained by simple circuit configuration without causing a disturbing noise due to the distortion and the transient characteristic of a collector current and a damper diode current, etc., onto a reception screen. |
