Abstract
A capacitively coupled square wave generator provides a steady state sinusoidal current flow in a deflection winding of a cathode ray tube. The deflection winding, the capacitive coupling and an additional capacitor form a tank circuit which filters out the odd harmonics of the square wave generator to provide a sinusoidal current in the deflection winding to produce bidirectional scanning.
