Read each question carefully and provide your answers in the spaces provided. Show your work where applicable.
1. Which logic gate produces a HIGH output only when all its inputs are HIGH?
OR gate
AND gate
NOT gate
XOR gate
2. The output of a NOR gate is HIGH if:
All inputs are LOW
All inputs are HIGH
At least one input is HIGH
Inputs are different
3. A gate is often referred to as an inverter.
4. The output of an XOR gate is HIGH if an number of its inputs are HIGH.
5. A truth table lists all possible input combinations and the corresponding output.
6. Draw the symbol for an AND gate and a NOT gate. Label their inputs and outputs.
7. Construct the truth table for a 2-input XOR gate.
8. A NAND gate is a universal gate, meaning any other logic gate can be implemented using only NAND gates.
True
False
9. The output of an OR gate is LOW only when all its inputs are LOW.
True
False
Match the logic gate with its Boolean expression.
10. AND Gate
a. Y = A + B
11. OR Gate
b. Y = A'
12. NOT Gate
c. Y = A ⋅ B
