Remember, use on only one side of the paper and staple them together. Only use a calculator to CHECK your work, not to DO your work. 1. Using only 2-input NOR gates (as many as you like for each part), build a circuit that is equivalent to the following circuits. [Hint: Connecting a signal to both inputs of a gate is acceptable.] (8 pts.) a. An inverter (Input x and output x’) b. 2-input AND gate (Inputs: x, y and output F = x and y) c. 2-input OR gate (Inputs: x, y and output F = x or y) d. Could a, b, and c, be accomplished using only NAND gates? 2. Use the theorems of Boolean algebra to find minimal SOP or POS expressions for each of the following logic functions: (10 pts.) a. F = (A+B )C D + C (A+B’)D + D(A+B ) b. )) ( ( ) ( ) ( z w x y x z w y x w y x w G + + + + + + = 3.
