Abstract:
A comparator for receiving a string of binary bits and for comparing the bits to determine the relative quantities of logic 0's and 1's, said comparator including:a plurality of energy emitting transducer elements each for receiving a respective bit of said string, and each for outputting energy having a first detectable characteristic on receiving a logic â€œ0â€  and for outputting energy having a second detectable characteristic on receiving a logic â€œ1â€ , said second detectable characteristic distinguishable from said first detectable characteristic, sensor means for detecting the energy emitted from said plurality of transducers and for providing respective intensity signals indicative of respective intensities of the energy of said first and second characteristic respectively, and output means responsive to said intensity signals for outputting an output signal indicating whether the number of logic 0's is greater than or less than the number of logic 1's.
