Logic Gates and Circuits Quiz

What is a logic diagram sometimes referred to as?

• Algorithm

• Truth table

• Circuit diagram

• Flowchart

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

• True

• False

• Undefined

• Same as input

Which condition will result in a true output for an AND gate?

• One input is true and one is false

• Both inputs are true

• At least one input is true

• Both inputs are false

For an OR gate, when is the output false?

• When one input is true

• When both inputs are false

• When both inputs are true

• When one input is false

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

• Undefined

• False

• True

• Same as input

How does a NOR gate operate compared to an OR gate?

• It outputs true when both inputs are true

• It outputs false when both inputs are false

• It reverses the output of an OR gate

• It has the same output as an OR gate

What is the unique feature of an XOR gate?

• It outputs true only when both inputs are true

• It outputs true only when both inputs are false

• It outputs true when exactly one input is true

• It outputs false when both inputs are true

What mnemonic device is suggested for remembering the NAND gate symbol?

• Think of the letter X

• Think of the letter T

• Think of the letter O

• Think of the letter D

Which gate is the only one with a single input?

• XOR gate

• NOT gate
