<p>ID-2712 QUASI FEEDBACK HORIZONTAL SCAN LINEARIZATION FOR CATHODE RAY TUBES A horizontal scan linearization circuit generates a linear ramp voltage during the active picture scan interval, which is compared to the non-linear ramp current of a cathode ray tube yoke circuit. The difference signal is fed back to the yoke circuit via a damper diode and is selectively added to the non-linear yoke current to correct the non-linearity.</p> |
