Abstract
A wide-angle kinescope deflection arrangement using an S-capacitor for correction over a major central portion of the scan has a residual compression of the display at the extremes of the scan. A saturable reactor is coupled in series with the deflection winding and saturates near the extremes of the scan due to the large deflection current. The reduced impedance of the reactor in series with the deflection winding causes the time rate of change of the deflection current to increase at the scan extremes and thereby linearizes the display.
