AQA 8525 CS 3.4.2 Logic Gates and Circuits (C&D Video)

What is the function of a NOT gate in a logic circuit?

• Reverses the input

• Combines two inputs

• Allows either input to be on

• Flips the output

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

• False

• True

• 1

• 0

What is the function of an XOR gate?

• Flips the output if both inputs are 1
