ABSTRACT:
An optical comparator for comparing two aligned sets of digital signals and for indicating the degree of similarity therebetween comprises a plurality of comparator cells each having two comparator inputs. Each comparator cell includes a multicolor light emitting diode adapted for emitting light of a first color when the first input is activated, light of a second color when the second input is activated, light of a composite color when both inputs are activated, and no light when no input is activated. Means are provided for absorbing light of the composite color whereby no light is emitted from a comparator cell in which the inputs are of equal activity. A light sensor is provided for monitoring total light output from a plurality of comparator cells. Light measured by the light sensor indicates the number of comparator cells having inputs of unequal activities and hence is representative of the degree of similarity between the two sets of signals.
