1. A method comprising:
detecting, by a processor, an initial insertion of an alternating current (AC) adapter;
determining an identifier associated with the AC adapter;
determining a parameter for filtering noise generated by the AC adapter based on the identifier; and
filtering the noise generated by the AC adapter by applying the parameter, wherein the filtering of the noise generated by the AC adapter includes adjusting a touch controller's analog front end frequency and digital filter integration time.
