Abstract
An embodiment of a method for detecting noise for a capacitance sensing panel may comprise generating an input signal based on a noise signal, performing a series of measurements for measuring capacitances from a capacitive sensor sensitive to the noise signal, and controlling timing for at least one of the subconversions based on the input signal.
