PCT No. PCT/US93/11995 Sec. 371 Date Jul. 7, 1995 Sec. 102(e) Date Jul. 7, 1995 PCT Filed Dec. 8, 1993 PCT Pub. No. WO95/16273 PCT Pub. Date Jun. 15, 1995A differentiation network differentiates a retrace pulse signal to produce a narrower pulse during the first half of retrace that is coupled to an input of a convergence amplifier. The convergence amplifier is coupled to a convergence winding to produce a convergence current. The narrower pulse produces an overshoot at the amplifier input and, thereby, speeds up the response time to the convergence amplifier.
