In a ripple counter, the propagation delay generally?

  • AIs independent of the number of stages
  • BAccumulates through successive flip-flop stages
  • CBecomes exactly zero
  • DOccurs only in the first stage
Report an error
Correct Answer: B. Accumulates through successive flip-flop stages
Explanation: Ripple counters are asynchronous; each stage is triggered by the preceding stage, so propagation delays accumulate.
Reference: Standard digital electronics: asynchronous counters
