a) In order to build a counter that produces the following output sequence at its Q outputs: 2-3-4-5-6-7-8-9-2-3..., how many flip-flops are needed? Explain.
b) What is the modulus of this counter? How does this relate to the clock frequency division that this counter can provide? Explain.
c) At what number does this counter reset to start the sequence over again? Explain.
