Design 2-bit comparator using gates

Answer 1

2 bit comparator = 1bit magnitude comparator +1 bit magnitude comparator

if A>B =A(~B)(B bar);

if A<B = ~A.B;

A==B = AB + (~A)(~B);

block of instruction shown above is for 1 bit comparator

means if A>B ==true then High bit is set on (A>B) output.

if A<B true then high bit is set on (A==B) output,

If we cascade two 1 bit comparator then we can design 2-bit comparator...
