ABSTRACT:
A television kinescope deflection circuit having improved linearity includes a deflection winding coupled in series with a first capacitor. A deflection switch and retrace capacitor are coupled across the serial combination of the deflection winding and first capacitor. The first capacitor responds to the deflection current to form a linearizing signal which modifies the flow of deflection current to provide S-correction. The linearity correction is improved by a series-resonant circuit coupled in parallel with the first capacitor and tuned to the second harmonic of the deflection frequency.
