If the 5-bit ripple counter and 5-bit synchronous counter are having flip-flops with a propagation delay of 20 ns, the maximum delay in the ripple counter (x) and synchronous counter (y) will be:
  • a)
    x = 20 ns, y = 90 ns
  • b)
    x = 20 ns, y = 100 ns
  • c)
    x = 90 ns, y = 20 ns
  • d)
    x = 100 ns, y = 20 ns
Correct answer is option 'D'. Can you explain this answer?

Concept:
Ripple counter:
In the ripple counter, the clock signal is applied to the LSB flip-flop and the output of the flip-flop acts as the input clock pulse for the next flip-flop.
Hence, as the no. of the flip-flop increases, the delay in the ripple counter also increases.
The maximum delay in the ripple counter is given by:
Td = nTf
Synchronous counter:
In the synchronous counter, all the flip-flops have a common clock signal.
Hence, as the no. of flip-flops increases, the delay in the synchronous counter does not increase.
Td = Tf
Calculation:
Given, n = 5
Tf = 20 ns
For ripple counter:
Td = 5 × 20
Td = 100 ns
For synchronous counter:
Td = 20 ns
