Abstract:
Techniques for detecting noise with a capacitive sensing device. The includes driving a set of one or more sensor electrodes of a plurality of sensor electrodes with a sensing signal at a first frequency, receiving resulting signals based on the sensing signal for each of the one or more sensor electrodes driven, probing the set of one or more sensor electrodes to obtain a set of probing signals, and summing the probing signals of the set of probing signals to generate a noise-analysis signal.
