G.B + A.B.A.B - ABT 5 A3: Without using any formal methods, simplify the above diagram as much as possible. That is, if you see two inverters back to back, you can remove them, or, if you see a sub-circuit being reused, you can use the output from one instance of that sub-circuit, and eliminate the other. A4: Assuming that each NOR gate has a propagation delay of 1,: a) what is the propagation delay of your XOR gate from 0.2, and b) what is the propagation delay of your XOR gate from 0.3.
