Different ways of implementing a comparator?

Answer Posted / rohit jain

If we are talking about the Digital Comparator which
compares two binary digits (1 & 0) than we can implement
using a multiplexer.

Here A and B are the select lines of mux.
suppose A>B--------o/p=a1 (A,B)=(1,0)
A<B--------o/p=a2 (A,B)=(0,1)
A=B--------o/p=a3 (A,B)=(1,1) (0,0)

Is This Answer Correct ?    6 Yes 1 No
