on 2 327 68 655 36 and so on so if the sample has an amplitude of 491 52 327 68 163 84 or less will be sorted into the first bin if the sample has an amplitude larger than 491 52 but less than or equal to 819 2 655 36 163 84 it will be sorted into this second bin and so on and so forth therefore the probability density of each bin can be computed the probability density for the bin for each of the four ranges in this case is compute recursively as follows the bin that corresponds to the amplitude of the signal at time t is added a count a the rest of the bins will be reduced by the quantity p m 1 u2212 u03b1 where m is the bin number which ranges from 1 to m where m is the total number of bins p m is the probability density of bin m this process is further illustrated by the equations below wherein the largest amplitude of a block can belong to bin b 13 in this case where p m is the probability density of bin m and p 13 is probability density of bin 13 whereas the bin number m ranges from 1 2 3 m excluding m 13.
