  • AND and OR gates have 2 or more inputs and produce a single output
  • 2 input NOT gate has 2 inputs (A and A) and produces 2 outputs (0 and 1)
  • The 2 input NOT gate performs the logical NOT operation on the inputs
• How do the different logic gates (AND, OR, NOT) in the circuit contribute to the overall output?

  • The AND gates (.) combine the inputs to produce intermediate outputs
