Exploring Logic Gates in Digital Electronics

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

• 0

• 1.5

• true

• 1

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

• XOR gate

• AND gate

• OR gate

• NAND 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 combine multiple input signals.

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

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

How many inputs can a NAND gate have?

• Two or more inputs

• One input

• Only digital inputs

• Three inputs

What is the truth table for an OR gate?

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

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

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

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

Which logic gate is equivalent to a NOR gate followed by a NOT gate?

• XOR gate

• AND gate

• OR gate

• NAND gate

What is the output of an XOR gate when both inputs are the same?

• 0

• Both inputs are ignored

• 2

• 1

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

• The number of inputs a single output can drive.

• The maximum voltage a circuit can handle.

• The total number of outputs from a single input.

• The speed at which a signal travels through a wire.

What is the primary difference between a NAND gate and a NOR gate?

• NAND gate outputs true with at least one false input; NOR gate outputs false with at least one true input.

• NAND gate and NOR gate are identical in function and output.

• NAND gate outputs true with all true inputs; NOR gate outputs false with all false inputs.

• NAND gate outputs false with all true inputs; NOR gate outputs true with all false inputs.

How can you implement a logic function using only NAND gates?

• NAND gates cannot be used to create OR operations.

• You can only use AND gates to implement logic functions.

• You can implement any logic function using combinations of NAND gates to create NOT, AND, and OR operations.

• You need at least one type of gate other than NAND to implement any logic function.
