Abstract
A vertical deflection amplifier drives a vertical deflection coil according to a ramp input signal and has a current sensing resistor providing a feedback signal. The vertical deflection coil is subject to crosstalk or excitation by a horizontal deflection coil. A compensation network is coupled between a source of the horizontal deflection signal and the current sense resistor, and has a network that produces a corrective current in the current sense resistor to substantially cancel horizontal rate crosstalk component from the feedback signal.
