Abstract
PURPOSE: To ensure the decision of the scale with a simple and small-scale constitution by reversing only the code bit of each digital numerical value to be compared and then carrying out the scale decision with the code bit used as the bit information containing the bit importance and through the absolute value comparator.
CONSTITUTION: Only the code bit of digital numerical value A, B and C each is reversed through reverse circuits 3W6, and these output are compared through absolute value comparator circuits 7 and 8 to be delivered when A≤B and B≤C are satisfied. The output signals of circuits 7 and 8 are supplied to AND gate 9 and show that A≤B≤C is satisfied to deliver the decision signal. As a result, the complements of value A, B and C to be compared is not required, thus realizing a simple-structure and amall-scale digital comparator circuit. Furthermore, the comparison and decision can be accelerated since only the code bit is reversed.
