Abstract
In a method of determining noise templates for use in capacitive sensing, a plurality of changes of capacitance are acquired, which include noise components, from a plurality of sensor electrodes in a sample capacitive sensor. Each of a plurality of substantially orthogonal noise templates is determined based on the acquired plurality of changes in capacitance. Multiple substantially orthogonal noise templates are selected, from the plurality of substantially orthogonal noise templates, to be used as a set of substantially orthogonal noise templates for reduction of the noise components of the acquired plurality of changes of capacitance.
