摘要: Proximity detection is accomplished by determining with a moving average calculation a moving average level of input data; setting a threshold level in response to the average level and a sensitivity factor; producing a proximity detection output when the input data meets the threshold level; and changing the weighting used by the average level calculation in response to a proximity detection output.
