Abstract
Embodiments of the disclosure provided herein provide a device and method of using the device that is able to improve the detection of user input provided to an input device while one or more sources of noise are present during the detection process. One or more of the embodiments disclosed herein may include a scanning process and a signal processing technique that is able to more reliably detect the presence and position of an input object by reducing the effect of noise on a resulting signal that is generated during a capacitive sensing process. In some configurations, the scanning and signal processing techniques disclosed herein can be improved by increasing a capacitive sensing device's ability to detect the presence of an input object by improving the signal-to-noise ratio of the data collected during a capacitive sensing process.
