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 18):
The method of  claim 10 , further comprising:\n applying a second matched filter that is phase-shifted with respect to the matched filter by approximately 90 degrees to the sigma-delta quantized signal to generate a quadrature-phase filtered sigma-delta quantized signal.
