Abstract
An electronic device is disclosed comprising an acceleration sensor operable to generate an acceleration signal, and a free fall detector operable to detect a free fall event in response to the acceleration signal. A frequency response of the acceleration signal is measured, and the free fall detector is disabled when a magnitude of the frequency response within one of a plurality of frequency bands exceeds a threshold, wherein each frequency band corresponds to one of a plurality of normal operating modes.
