ABSTRACT OF THE DISCLOSURE This invention relates to a novel drive circuit for use with a cathode ray tube display circuit having a yoke. The drive circuit includes a receiving means for an input signal, a linear ramp signal generator and a solid state shaping means for shaping the linear ramp to compensate for nonlinearities. Summing means is provided to produce a compensated drive signal and the yoke is driven according to the signal produced. The cathode ray tube utilizing this drive circuit produces a high frequency display which has unparalleled clarity and resolution when compared to the prior art devices.
