Abstract
Described is a touch-sensitive apparatus including a plurality of drive electrodes and control circuitry is configured to: apply time-varying voltage signal(s) to groups of neighbouring drive electrodes for a first time period; perform a first measurement on a receiver electrode during the first time period; apply time-varying voltage signal(s) groups of neighbouring drive electrodes for a second time period; perform a second measurement on the receiver electrode during the second time period; and determine a resultant signal corresponding to the mutual capacitance between the first group of neighbouring drive electrodes and the receiver electrode based on both the first measurement and the second measurement. Further described is a corresponding method for determining the presence of a touch on a touch-sensitive element.
