  • Question
  • The process of designing a synchronous counter that will count in a nonbinary manner is primarily based on:


  • Options
  • A. external logic circuits that decode the various states of the counter to apply the correct logic levels to the J-K inputs
  • B. modifying BCD counters to change states on every second input clock pulse
  • C. modifying asynchronous counters to change states on every second input clock pulse
  • D. elimination of the counter stages and the addition of combinational logic circuits to produce the desired counts

  • Correct Answer
  • external logic circuits that decode the various states of the counter to apply the correct logic levels to the J-K inputs
