<p>The horizontal ramp correction has a horizontal ramp current sweep (iramp). The ends of the current ramp are modified to provide a corrected ramp sweep profile (icor). The corrected profile is applied to a multiplier circuit (5) squaring the input signal and producing a parabolic response (p"). The parabolic response is then applied to a modulator which provides the sweep to the TV Cathode Ray Tube.</p> |
