#3 Logic Gates

What is the primary function of a NOT gate in logic circuits?

• It outputs true if both inputs are true.

• It outputs true if at least one input is true.

• It combines two input signals.

• It reverses the input signal.

What is the output of a NOT gate when the input is 1?

• The output alternates

• The output is unchanged

• 0

• 1

How does an AND gate output a true signal?

• If the inputs are alternating in signal.

• If both inputs are true.

• If both inputs are false.

• If at least one input is true.

Which logic gate would you use to ensure output is true only when both inputs are true?

• XOR gate

• AND gate

• NOT gate

• OR gate

What condition must be met for an OR gate to output a true signal?

• None of the inputs should be true.

• Both inputs must be true.

• Both inputs must be false.

• At least one input must be true.

Which gate is described as having an output of true when at least one of its inputs is true?

• NOT gate

• NAND gate

• AND gate

• OR gate

How does the output of an XOR gate differ when both inputs are true compared to an OR gate?

• XOR outputs true, OR outputs false.

• Both output false.

• Both output true.

• XOR outputs false, OR outputs true.

In a logic circuit, what does the XOR gate do differently than the OR gate when both inputs are 1?

• No output

• Outputs 0

• Outputs 1

• Outputs alternate between 0 and 1

What mnemonic can help remember the shape of an XOR gate?

• The shape of an 'X'

• The shape of an 'O' with an extra line

• The shape of a 'T'

• The shape of a 'D'

What advanced logic gate is described as a combination of an AND gate followed by a NOT gate?

• XOR gate

• NAND gate

• NOR gate

• OR gate
