Abstract
A method and apparatus in an electronically controlled system such as a portable computer are provided for minimizing effects of noise picked up by an input device such as a touch-sensitive capacitive coupling input pad where a conductive stylus may be used on the pad to control the cursor movement on a display device. The present invention removes the cursor jitters on the display device that is associated with the input device and provides for quick cursor responses corresponding to quick motion input by the conductive stylus on the input pad.
