Abstract:
A processing system that includes a sigma-delta converter and a filter unit that applies a matched filter to the output of the sigma-delta converter. The processing system drives sensor electrodes for capacitive sensing and receives resulting signals with the sensor electrodes in response. The processing system applies these resulting signals to sigma-delta converters. The matched filter boosts the signal-to-noise ratio of the signal received from the sigma-delta converter, thereby improving the ability to sense presence of an input object. The filter unit may apply different, customized matched filters for different capacitive pixels to improve the signal-to-noise ratio of each capacitive pixel in a customized manner.

Claim (Index 13):
The method of  claim 12 , wherein:\n the discrete time cumulative sum signal comprises a series of values, each value being a cumulative sum of a baseline sigma-delta quantized signal up to a phase index corresponding to the value.
