A 4-bit ripple counter is driven by a 160 kHz clock. What is the frequency at the output of its most significant flip-flop?

  • A80 kHz
  • B20 kHz
  • C40 kHz
  • D10 kHz
Correct answer: D

Explanation

Each flip-flop divides the frequency by 2, so four stages divide by 16 and 160 kHz becomes 10 kHz.
