Abstract
A horizontal position control for a television waveform monitor includes a potentiometer that has a substantially linear input position/output voltage transfer function, and a circuit for reducing the sensitivity of the horizontal position control over a predetermined range of input positions of the potentiometer. The reduced sensitivity is preferably provided over a band approximately at the center of the range of horizontal positions covered by the horizontal position control.
