1. A method of digitally processing a signal comprising:

  • sampling the signal and dividing the samples into windows;

    associating one of at least three values with a respective window based upon whether the samples in the window are relatively constant, incremental, or decremental, to thereby generate an approximation vector;

    determining locations of thresholds in the approximation vector to generate a threshold position vector that indicates the locations of thresholds in the approximation vector; and

    assigning threshold values to the threshold positions in the threshold position vector to thereby generate a set of threshold values.
