I have a quetion that Output E indicates A= B (eg. A1=A0=B1=B0=1, E=1)
This is expression for E i get....
E=A1'A0'B1'B0'+A1'A0B1'B0+A1A0'B1B0'+A1A0B1B0
Here is the circuit that i draw:

 

oops

 

I have draw a circuit based on the expression for Output E that indicates A=B.
But now , i have to draw inequlty function of Output G(by using no more than 5 gates) that indicates A>B to my circuit.
The observations:
1. WhenA1 is not equal B1 andA1=1 , G=1(regardless of A0 and B0)
2. However if A1=B1,G=1 only if A0 is not equal to B0 andA0=1

Here is my circuit of Output E:
