  • Question

  • One of the major drawbacks to the use of asynchronous counters is that:


  • Options
  • A. low-frequency applications are limited because of internal propagation delays
  • B. high-frequency applications are limited because of internal propagation delays
  • C. Asynchronous counters do not have major drawbacks and are suitable for use in high- and low-frequency counting applications.
  • D. Asynchronous counters do not have propagation delays, which limits their use in high-frequency applications.

  • Correct Answer
  • high-frequency applications are limited because of internal propagation delays
