Abstract
A circuit is shown for compensating for rapid changes in D.C. levels in high pass filter coupled vertical deflection circuits. It features a second high pass filter that applies a D.C. signal having a second level change so that the first change is cancelled out. The second change can be applied directly to the first change with opposite polarity, or to the emitter of a transistor that receives the first change at its base with the same polarity.
