  • Question

  • A MOD-16 synchronous counter has inputs labeled A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset. These inputs would most probably be used to:


  • Options
  • A. reset the counter to 0000 at the end of each count cycle
  • B. preset the counter to a value determined by the A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset inputs any time the A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset is active-HIGH
  • C. preset the counter to a value determined by the A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset inputs any time the A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset is active-LOW
  • D. reset the counter to 0000 any time A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset is active-HIGH and A MOD-16 synchronous counter has inputs labeled . These inputs would most probably be used to: reset is active-LOW

  • Correct Answer
  • reset the counter to 0000 any time is active-HIGH and is active-LOW
