Abstract
Systems and methods for detecting a user's finger or other elements may be provided. In some embodiments, the system may include a memory, a sensor area, and a processor. The sensor area may include a set of receiving electrodes which may be partitioned among a plurality of electrode groups. The system may be configured to process signals received by the electrode groups by modulating the signals received from each electrode of the respective electrode group according to a modulation pattern, and demodulating the signals, or values derived therefrom, received from each electrode of the respective electrode group according to a demodulation pattern. The electrode groups may be at least partially interleaved.
