Abstract
A processing system comprises a sensor module and a determination module. The sensor module comprises sensing circuitry coupled to sensor electrodes of a sensor electrode pattern. The sensor module is configured to: drive a modulated signal onto a first sensor electrode of the sensor electrode pattern; receive first resulting signals from the first sensor electrode; and receive second resulting signals from a second sensor electrode of the sensor electrode pattern. The second resulting signals comprise effects corresponding to the modulated signal, and the first resulting signals and the second resulting signals are simultaneously received. The determination module configured to determine a change in capacitive coupling between an input object and the first sensor electrode based on the first resulting signals and a change in capacitive coupling between the first and second sensor electrodes based on the second resulting signals.
