Abstract
A linearity correction circuit for use with the horizontal deflection circuit of a television receiver comprises an inductor having two inductor portions. A capacitor, coupled to the S-shaping capacitor of the horizontal deflection circuit, is charged through one portion of the inductor during the horizontal trace interval, and discharged through another portion of the inductor during the horizontal retrace interval in order to provide linearity correction. The inductor may be tapped to allow charge/discharge current switching during the trace interval without introducing beam velocity modulation errors so that the linearity correction circuit may be efficiently combined with horizontal driver circuitry.
