Logic Gates and Basic Electronics

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

• 1

• true

• 1.5

• 0

How many inputs can an OR gate have?

• An OR gate can have multiple inputs, commonly 2 to many.

• An OR gate can have a maximum of five inputs.

• An OR gate can only have one input.

• An OR gate can have exactly three inputs.

What is the output of a NOT gate if the input is 0?

• 1

• -1

• 0

• 2

If one input of a NAND gate is 1 and the other is 0, what is the output?

• 2

• 1

• 1.5

• 0

What is the truth table for an AND gate?

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

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

Explain the difference between an OR gate and an NOR gate.

• An OR gate and a NOR gate both output true only when all inputs are true.

• An OR gate outputs true for at least one true input, while a NOR gate outputs true only when all inputs are false.

• An OR gate requires all inputs to be true to output true, while a NOR gate outputs true for any true input.

• An OR gate outputs false for all inputs, while a NOR gate outputs true for at least one true input.

What is the output of an OR gate if both inputs are 0?

• 1

• 0

• -1

• 0.5

How does a NAND gate differ from an AND gate?

• A NAND gate outputs the opposite of an AND gate; it outputs false only when both inputs are true.

• A NAND gate outputs true only when both inputs are true.

• A NAND gate has no relation to an AND gate and operates independently.

• An AND gate outputs true when at least one input is true.

What is the significance of logic gates in digital circuits?

• Logic gates are irrelevant to digital circuit design.

• Logic gates are essential for processing binary data in digital circuits.

• Logic gates are used only in analog circuits.

• Logic gates are primarily for storing data in memory.

Can a combination of AND, OR, and NOT gates create any logical function?

• Yes, a combination of AND, OR, and NOT gates can create any logical function.

• No, only AND gates can create logical functions.

• Yes, but only for specific functions.

• No, OR gates alone can create any logical function.
