1. Given the asynchronous ripple counter in Figure 1, give the output waveforms for Qo, Q₁, and Q₂ for 16 clock cycles. CLK Do с 20 20 D₁ с 2₁ D₂ C 2₂ Figure 1 2. Using the asynchronous ripple counter in Figure 1 and assuming that the propagation delay from an input clock to a change in the output of Q is 9ns, what is the worst-case delay (i.e. longest delay) between an input clock pulse and the counter being in a final state. Give which state(s) of the counter have the worst-case delay. 3. If the counter from Problem 2 was synchronous, what would the worst cast propagation delay be?
