Comparator is used to compare two binary numbers, 1-bit comparator circuit is used to compare 1-bit binary numbers.

A	B	f(A>B)	f(A=B)	f(A<B)</th>
0	0	0	1	0
0	1	0	0	1
1	0	1	0	0
1	1	0	1	0

Now find the equations for each f(A>B), f(A=B), f(A<B) using k-maps.</p>

Equation is $A+\bar B$

Equation is $\bar A\bar B+AB=A\odot B$

Equation is $\bar AB$
