circuits using only NOR gates; Apply DeMorgan Theorems Equipment: Digital trainer, 7402, 7400, 7404 Procedure: Part A: 1.Connect the circuit presented in Figure 1 using a 7402 chip. Fill in the truth table. Is this a 4-input NOR Gate? Explain. C Review NOR gates (universal gates); Build digital logic D NOR2 NOR2 NOR2 Figure 1 2. For the circuit shown above, write the Boolean expression for Y and express it as SOP terms (Using DeMorgan's theorems plus any other Boolean algebra theorems you might need.) 3. Show how you can wire a 4-input NOR Gate using any chips available in the lab. Part B: 1. Connect the following circuit using only one 7402 chip. Fill in a truth table. Derive the Boolean equation for Z and express it in SOP terms. A (al B O O INV Figure 2 NOR2 Part C: 1. Suppose you need a 3-input NOR gate for a circuit, but all you have available are 7400 and 7420 ICs. Show how you could obtain the required NOR using these NAND gates. (HINT: apply DeMorgan's theorem). Note: Writing for part C is optional. Part D: 1. Wire a 3-input NOR gate using only a 7402 chip (quad 2-input NOR gates). circuits using only NOR gates; Apply DeMorgan Theorems Equipment: Digital trainer, 7402, 7400, 7404 Procedure: Part A: 1.Connect the circuit presented in Figure 1 using a 7402 chip.
