  • Question
  • Which of the following describes the operation of a positive edge-triggered D-type flip-flop?


  • Options
  • A. If both inputs are HIGH, the output will toggle.
  • B. The output will follow the input on the leading edge of the clock.
  • C. When both inputs are LOW, an invalid state exists.
  • D. The input is toggled into the flip-flop on the leading edge of the clock and is passed to the output on the trailing edge of the clock.

  • Correct Answer
  • The output will follow the input on the leading edge of the clock.
