40 TOP LOGIC GATES Online Test – Questions and Answers 1. What input values will cause an AND logic gate to produce a HIGH output? All inputs are HIGH At least one input is LOW At least one input is HIGH All inputs are LOW 2. The basic logic gate whose output is the complement of the input is the AND gate INVERTER gate OR gate comparator 3. Exclusive-OR (XOR) logic gates can be constructed from what other logic gates? AND gates and NOT gates OR gates and NOT gates AND gates, OR gates, and NOT gates OR gates only 4. A NAND gate has LOW inputs and a LOW output HIGH inputs and a HIGH output LOW inputs and a HIGH output None of the these 5. How many NAND circuits are contained in a 7400 NAND IC? 1 2 3 4 6. The logic gate that will have HIGH or “1” at its output when any one of its inputs is HIGH is a(n) NOT gate NOR gate AND gate OR gate 7. How many truth table entries are necessary for a four-input circuit? 4 8 12 16 8. If a signal passing through a gate is inhibited by sending a low into one of the inputs, and the output is HIGH, the gate is a(n): NAND OR NOR AND 9. A single transistor can be used to build which of the following digital logic gates? OR gates AND gates NOT gates NAND gates 10. The output will be a LOW for any case when one or more inputs are zero in a(n): NOT gate AND gate OR gate NAND gate Loading … Question 1 of 10
