Zusammenfassung:In accordance with an embodiment, a method of performing a measurement with a capacitive sensor includes generating a periodic excitation signal that includes a series of pulses and smoothing edge transitions of the series of pulses to form a shaped periodic excitation signal that includes a flat region between the smoothed edge transitions. The method further includes providing the shaped periodic excitation signal to a first port of the capacitive sensor and measuring a signal provided by a second port of the capacitive sensor.
