Handling of electromagnetic interference in an electronic apparatus

摘要

The present invention provides a touch-sensitive apparatus and a method for determining a coordinate position in response to a proximity detection for the touch-sensitive apparatus. The method comprises the steps of: evaluating a plurality of designed measurement modes by measuring noise over a plurality of measurement cycles when a proximity event on the touch-sensitive apparatus has been detected; selecting an optimal measurement mode from the plurality of designed measurement modes; assigning the optimal measurement mode to be a working measurement mode; performing the proximity detection for the touch-sensitive apparatus in use of the working measurement mode; and calculating the coordinates of the touched position based on results obtained with the working measurement mode.
