Abstract:
1. A multi-channel signal processor comprising: a signal memory for receiving and storing a plurality of data for a reference channel and each of two or more additional channels for a data set; a first relative array for storing a plurality of first related values, the plurality of first related values being established by obtaining a first relative function relating a second channel of the at least two or more additional channels to the first reference channel and being distributed symmetrically about an identity value from reciprocal values of the plurality of first related values; a second relative array for storing a plurality of second related values, the plurality of second related values being established by obtaining a second relative function by relating a third channel of the at least two or more additional channels to the first reference channel and being distributed symmetrically about an identity value from reciprocal values of the plurality of second related values; and a channel comparator for forming one or more histograms for determining the distribution of the first and second related values.
