AQA - Section 4 - Truth Tables

What are the possible inputs for a single input logic gate?

• On and Off

• 0, 1, and 2

• True and False

• 0 and 1

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

• 1

• 0

• True

• False

How many possible input combinations are there for an AND gate?

• 2

• 3

• 4

• 5

For an OR gate, if one of the inputs is 1, what is the output?

• 0

• False

• 1

• True

What differentiates an XOR gate from an OR gate in terms of output?

• XOR outputs 1 when both inputs are 1

• XOR outputs 0 when both inputs are 1

• XOR outputs 1 when both inputs are 0

• Outputs are the same
