Abstract

An apparatus and method for filtering data that include retrieving a plurality of data samples from memory; computing a locus of the samples; computing a distance between an input value and the locus; comparing the distance between the input value and the locus with a first threshold value; applying a distance-based filter to the samples; and comparing an output value of the median filter with a second threshold value.
