Exploring Logic Gates in Digital Electronics

What is the output of an AND gate if both inputs are 1?

• 1

• 1.5

• 0

• true

Which logic gate outputs true only when all inputs are true?

• OR gate

• XOR gate

• AND gate

• NOT gate

What is the function of a NOT gate?

• The function of a NOT gate is to pass the input signal unchanged.

• The function of a NOT gate is to invert the input signal.

• The function of a NOT gate is to combine multiple input signals.

• The function of a NOT gate is to amplify the input signal.

How many inputs can a typical NAND gate have?

• 1 to 3 inputs

• Typically 2 to 4 inputs

• 5 to 6 inputs

• Only 2 inputs

What is the output of an OR gate if at least one input is 1?

• 1.5

• 1

• 2

• 0

Which logic gate is known as the universal gate?

• NAND gate

• XOR gate

• AND gate

• OR gate

What is the truth table for a NOR gate?

• | A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 1 | | 1 | 1 | 0 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 1 | | 0 | 1 | 1 | | 1 | 0 | 0 | | 1 | 1 | 1 |

• | A | B | Output | |---|---|--------| | 0 | 0 | 1 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 0 |

How does an XOR gate differ from an OR gate?

• An XOR gate outputs true for any true input, while an OR gate requires all inputs to be true.

• An XOR gate differs from an OR gate in that it requires an odd number of true inputs to output true, whereas an OR gate outputs true for any true input.

• An XOR gate can only have one input, whereas an OR gate can have multiple inputs.

• An XOR gate outputs false when both inputs are true, while an OR gate outputs true in the same case.

What is the output of a NAND gate when both inputs are 0?

• 1

• -1

• 0

• 1.5

In digital circuits, what does the term 'fan-out' refer to?

• The term 'fan-out' refers to the number of inputs a single output can drive in digital circuits.

• The number of outputs a single input can drive.

• The maximum voltage a circuit can handle.

• The total number of gates in a circuit.
