Questions and Answers

What is a switching circuit?

  • A circuit with only one input and one output
  • A circuit with both analog and digital inputs
  • A circuit that has no memory
  • A circuit that can only take on discrete values (correct)

    • What is the main difference between a combinational circuit and a sequential circuit?

  • A sequential circuit has no memory
  • A sequential circuit has no inputs
  • A combinational circuit has no memory (correct)
  • A combinational circuit has no inputs

    • How do the output values of a combinational circuit depend on the inputs?

  • They depend on the future values of the inputs
  • They depend on both present and past input values
  • They depend only on the present value of the inputs (correct)
  • They do not depend on the inputs

    • What does it mean for a sequential circuit to have memory?
