    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.

    摘要: A reduced chop rate analog to digital converter technique including selectively weighting input samples to a digital filter, alternately inverting the polarity of an input error into positive and negative error components; and generating the positive and negative error components in a plurality of time response intervals of the digital filter in which the sum of the weights of the positive and negative error components are substantially equal.
