<p>An apparatus for image enhancement in a cathode ray tube (CRT) display comprises an amplifier (100, 200, 300, 400) for a scanning velocity modulating signal. The scanning velocity modulating signal has an AC component (Vac) and a DC value (Vdc). A feedback circuit (500) is responsive to power dissipation in the amplifier for controlling the AC component (Vac) and the DC value (Vdc) with a first control signal (I1), and controlling only the DC value (Vdc) with a second control signal (Icomp). <IMAGE></p> |
