Abstract
An automatic S-correction circuit for a deflection circuit includes an active source of generally sawtooth current having an amplitude that is proportional to the deflection frequency. The sawtooth current and a deflection current that flows in a deflection winding are combined as a current flowing in an S-capacitor that develops a parabolic voltage. The amplitude of the parabolic voltage is automatically adjusted to be at a level that is required for maintaining proper S-correction for any deflection frequency within a continuous, wide range of frequencies.
