3. A logic gate is an elementary building block of a circuit.
4. The two basic logic levels are represented by 0 and 1, often referred to as and .
5. The Boolean expression for an OR gate with inputs A and B is Y = .
6. A NAND gate is an inverted AND gate.
True
False
7. An XOR gate produces a high output when both inputs are the same.
True
False
8. Draw the standard logic symbol for an AND gate with two inputs and one output.
9. Construct the truth table for a 2-input NOR gate.
Match each logic gate with its corresponding Boolean expression.
10. AND Gate
