ABSTRACT:
A deflection waveform generator uses a low voltage accurate capacitor to integrate the yoke deflection current and derive a parabolic waveform for "S" correcting the basic sawtooth deflection waveform. This parabolic waveform is fed back to the inverting input of a balanced operational integrating amplifier, the inverting input also having the integrating network coupled thereto. The polarities of the signal waveforms at the inverting input are such that the combined signal fed through the integrating network creates a "S" corrected sawtooth yoke deflection current which drives the electron beam in a manner which compensates geometric distortion inherent in the CRT.
