Abstract
A horizontal deflection nonlinearity correction circuit utilizes horizontal retrace pulse energy to provide nonlinearity correction of the horizontal deflection current. An inductor stores retrace pulse energy during the horizontal retrace interval and releases the energy during the horizontal trace interval. Nonlinearity correction is accomplished by appropriate charging and discharging of the horizontal deflection circuit S-shaping capacitor. The nonlinearity correction circuit may be combined with horizontal driver circuitry to provide economy of circuit components.
