A four-bit ripple counter is driven by a 20-MHz clock signal. Draw the waveforms at the output

Question:

A four-bit ripple counter is driven by a 20-MHz clock signal. Draw the waveforms at the output of each FF if each FF has t_pd = 20 ns. Determine which counter states, if any, will not occur because of the propagation delays.
