Abstract
A digitizing panel responsive to a signal transmitted from a stylus for generating stylus position information is disclosed. The digitizing panel includes a coordinate generator for determining coordinate data indicative of a position of the stylus relative to the digitizing panel, a velocity calculator for determining a stylus velocity value based on the coordinate data, a mechanism for determining a filter bandwidth value based on the stylus velocity value, a filter for filtering the coordinate data wherein the filter has a predetermined bandwidth characteristic, and a mechanism for varying the predetermined bandwidth characteristic based on the filter bandwidth value. A method for filtering position data of a stylus associated with a digitizing panel is also disclosed.
