Abstract

A horizontal deflection circuit generates a horizontal deflection current in a deflection winding, during a trace interval and during a retrace interval of a deflection cycle. A transistor is responsive to a vertical rate parabola signal and to a negative feedback signal for producing a vertical rate parabolic modulation voltage at a collector of the transistor. A negative feedback network generates the feedback signal that is indicative of a current flowing in the transistor for increasing an output impedance at the collector of the transistor. An inductor is coupled to the collector of the transistor for producing in the inductor a modulation current to provide for side pincushion distortion correction in an East-West modulator.
