A method for reducing data in the form of successive groups of N values may comprise finding the largest X values of the N values of each group, setting all but the largest X values of each group equal to zero, averaging W respective ones of the N values to produce N average values, finding the largest Y of the N average values, where Y is less than X, and setting the largest Y of the N average values equal to a first binary value, and a reminder of the N average values equal to a second binary value.
