Claim 8:
9. The encoding unit of claim 7, wherein determining the representation of the respective relative energy difference, comprises:
a) setting the input vector as an upper level input vector;
b) finding a center boundary, if any, between input vector segments being at or closest on a first side to a center of the upper level input vector;
c) dividing the upper level input vector at the center boundary, if any, into two lower level input vectors;
d) calculating a representation of a relative energy difference between the two lower level input vectors if the center boundary exists; and
e) repeating the steps b)-d) of finding, dividing and calculating by re-setting the lower level input vectors as a respective upper level input vector, until all boundaries between input vector segments are provided with an associated representation of a relative energy difference.
