  • Vertical deflection circuit
    Patent number: 4810940
    Abstract: A vertical deflection circuit of the negative feedback type wherein a feedback signal, being generated at a terminal of a deflection current detector resistance connected in series with a vertical deflection yoke, is connected to negative feedback amplifier which guides the output of a sawtooth wave generating circuit through a third order distortion wave generating circuit. The third order distortion wave generating circuit imparts third order distortion of positive polarity to said feedback signals, so that third order distortion of negative polarity is imparted to the current of said deflection yoke, and whereby the third order distortion is compensated and extinguished on the CRT display.
