Abstract

A classifying system for determining with which group of a plurality of groups of reference file words a data word most closely compares and comprising a plurality of groups of comparison means each constructed to simultaneously and individually compare a different group of file words with said data word to produce a comparison pulse for each comparison of said data word with a file word. Means are provided for identifying each group of file words in which the comparison of not more than one file word with the data word produces a comparison pulse whose amplitude exceeds, in a given direction of polarity, the predetermined amplitude of a threshold signal, and further for identifying each of said one file words.
