Claim Text:
1. A method comprising: sequentially integrating and converting charge from each of a plurality of sensing capacitors in an array to generate digital data, the digital data including sample values corresponding to a respective measured capacitance for each of the plurality of sensing capacitors; forming a sliding window of the digital sample values using a sample aperture of size W, wherein W is an integer greater than 2, wherein a position of each sample value within the sliding window is based on a sequence in which it was generated, and wherein border values are mirrored to enable the sliding window to include W samples for each position of the sliding window; for each respective position of the sliding window: summing a plurality of the filtered sample values to form an accumulated sample value; and using the accumulated sample value to determined a position of at least one contact on the touch sensor array.
