Abstract: In one embodiment, a non-transitory computer-readable medium comprising logic is configured to, when executed by one or more processors, cause the one or more processors to perform operations comprising measuring samples from a touch sensor. Each sample is measured by determining, based on a first pattern of polarities, a polarity of a charging signal to be applied to an electrode of the touch sensor, the first pattern of polarities based on a signal associated with a noise source; applying the charging signal to the electrode, the charging signal, as applied, having the polarity determined based on the first pattern of polarities; and measuring a received signal from the touch sensor, the received signal resulting, at least in part, from the charging signal applied to the electrode. The operations comprise determining whether a touch event has occurred at the electrode by analyzing the received signals from the samples.
