Abstract
An apparatus includes multiple capacitive sensing elements coupled through a filter network. The apparatus can include a control device configured to excite the capacitive sensing elements with different scanning frequencies and determine capacitances corresponding to each of the capacitive sensing elements based on sensor responses to the excitation of the capacitive sensing elements with the different scanning frequencies and a configuration of the filter network.
