補正回路。[Claims for Utility Model Registration] A parabolic wave generating circuit receives a vertical frequency sawtooth wave, converts the sawtooth wave into a parabolic wave and outputs the parabolic wave, and modulates a horizontal deflection current by a horizontal deflection circuit with the parabolic wave. In addition to the deflection coil, in a left-right pincushion distortion correction circuit that corrects left-right pincushion distortion of a picture tube of a television receiver, the sawtooth wave is amplified and the amplitude of the amplified sawtooth wave is limited to create the parabolic wave creation circuit. A left and right pincushion distortion correction circuit with a limiter circuit input to the left and right pincushion distortion correction circuits.
