Design a circuit to compare two $2-$bit numbers A and B $($A $=$ a$1$ a$0$; B $=$ b$1$ b$0).$ The circuit has three outputs G $($greater than$),$ E $($equal to$)$ and L $($less than$)$ so that:

G $=1$ if A $>$ B$,$

E $=1$ if A $=$ B$,$ and

L $=1$ if A $<$ B$.$

Note: Inputs to the circuit must be named as a$1,$ a$0,$ b$1,$ b$0,$ G$,$ E and L$.$ Respect upper and lower cases.

Instructions to answer this question

$1)$ In the virtual machine, open VerilUOC$\_$Desktop and draw the circuit.
