Abstract
One or more computing devices, systems, and/or methods are provided. In an embodiment of the techniques presented herein, a touch detection system, comprises a touch sensor array comprising unit cells, a transmit sequencer configured to generate an excitation signal, an analog-to-digital-converter unit configured to measure responses of the unit cells to the excitation signal and, a processing unit configured to generate a first capacitance map based on the responses, filter the first capacitance map, by rows, in a first band pass filter to generate a second capacitance map, and detect a touch event based on the second capacitance map.
