If the number of bits to be compared is more than two bits, the truth tables and hence the circuit becomes more ... Thus , we can implement 3-bit comparator with some different approach. ... Let us assume A is greater than B. This condition can be written as Aagt;B=agt; A-B agt;0 =agt; A + B+ 1 agt; 0 v B+ 1 is 2a#39;s ... 5.21 shows the circuit diagram of comparator for n = 3.
