Electronics-Logic Gates Question and Answer
Electronics-Logic Gates Question and Answer
1. The output will be a LOW for any case when one or more inputs are zero in a(n):
- OR gate
- NOT gate
- AND gate
- NAND gate
2. 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):
- AND
- NAND
- NOR
- OR
3. A single transistor can be used to build which of the following digital logic gates?
- AND gates
- OR gates
- NOT gates
- NAND gates
4. The logic gate that will have HIGH or "1" at its output when any one of its inputs is HIGH is a(n):
- OR gate
- AND gate
- NOR gate
- NOT gate
6. Exclusive-OR (XOR) logic gates can be constructed from what other logic gates?
- OR gates only
- AND gates and NOT gates
- AND gates, OR gates, and NOT gates
- OR gates and NOT gates
8. 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
9. The basic logic gate whose output is the complement of the input is the:
- OR gate
- AND gate
- INVERTER gate
- comparator
10. What input values will cause an AND logic gate to produce a HIGH output?
- At least one input is HIGH.
- At least one input is LOW.
- All inputs are HIGH.
- All inputs are LOW.
