In a cascaded ripple counter, the overall propagation delay is the sum of the delays of all stages. If each of the four 4-bit ripple counters has a propagation delay of approximately 70 ns, then cascading four of them would add up linearly:
70
70ns×4=280ns
So, the correct answer is 280 nanoseconds.
70
70ns×4=280ns
So, the correct answer is 280 nanoseconds.
