Question: 6. True or false: In an asynchronous counter, all FFs change states at the same time. 7. Explain why an asynchronous (ripple) counter maximum frequency

6. True or false: In an asynchronous counter, all FFs change states at the same time. 7. Explain why an asynchronous (ripple) counter maximum frequency limitation decreases as more FFs are added to the counter. 8. Determine the maximum clock frequency (max) of a 4-bit ripple counter if each FF has a propagation delay time tpd = 25 ns (25 x 109 sec)
