ABSTRACT:
An evaluation circuit is depicted for evaluating the overall group similarity between a plurality of first signals with a plurality of second signals and for producing a signal based on the level of similarity or dissimilarity. Such an evaluation circuit includes a plurality of operator circuits each of which compares corresponding ones of the first and second signals and which outputs the result of that comparison to a single summary function circuit. The summary function circuit produces an output signal that corresponds to a weighted summary of the comparison results. Finally, a comparitor circuit compares the output from the summary function circuit with a criterion signal and, depending upon the desired degree of similarity produces a binary output signal whose value is based on the magnitude of the summary function output signal being greater than the magnitude of the criterion signal.
The evaluation circuit can be used to determine the similarity of the input signal to a stored signal and if the comparison is favorable to output the input signals. The evaluation circuit can also be used for storing a plurality of input signals depending upon the results of a comparison of those signals with a stored signal.
