Abstract
A wide-band horizontal linearity correction circuit includes: a primary line coil connected between a horizontal deflection yoke and an S-correction capacitor, the primary coil being wound around a first a core having a hysteresis characteristic; a secondary line coil wound around a second core adjacent the first core; a pair of permanent magnets of opposite polarities, disposed on either end of the first core; a microprocessor for supplying an analog linearity correction control signal in response to the variation of the frequency of a horizontal drive pulse signal; and a coil driver for driving the secondary line coil in response to the correction control signal supplied by the microcomputer. Accordingly, horizontal linearity can be corrected over an entire frequency band.
