Claim:
1. A method of performing a scan operation for a single-layer sensor array comprising transmit (TX) electrodes and receive (RX) electrodes, the method comprising a set of operations, including: (a) determining, by a processing device, whether to include a signal value for an RX electrode in a computation of a slope parameter value for a TX electrode; (b) computing, by the processing device, an index sum based on an index of the RX electrode when the signal value for the RX electrode is included in the computation of the slope parameter value for the TX electrode; (c) computing, by the processing device, a signal sum based on the signal value for the RX electrode when the signal value for the RX electrode is included in the computation of the slope parameter value for the TX electrode; and (d) computing, by the processing device, the slope parameter value for the TX electrode based on the signal sum and the index sum.
