Answer / guest

XOR each of 8 bits and outputs of XOR gates OR to get the
output. Output will become '0' when both are same.

Answer / srinivasulu

xor or x nor is same.but design considerations for xnor we
need extra gate.so xoris best

Answer / amareswar

pass input to XOR and give their outputs to OR gate, if u r
output is 0 both 8-bit signals are same.

OR
pass input to XNOR and give their outputs to AND gate, if u
r output is 1 both 8-bit signals are same.

Answer / gogulnath

by using both xor as well as comparator

Answer / ram dubey

i think we can use 8 bit comprator'

Answer / chandrashekar

i think we need to use xnor instead of xor just check
