Feel free to pull the pages apart if it makes it easier to refer to figures. Put your name on every loose page!!!

1.) Write the FF input functions (In any form):(6 pts)

JA =

KA =

DB =

2.) Write the output Function:(4 pts)

Z =

3.) Create the state table, including inputs and outputs(15pts)

4.) Draw the state diagram(5pts)

5.) Is this a Mealy or Moore Model circuit?(5 pts)

For the State Diagram Below, and using only T Flip Flops:

6.) Determine the state table(10 pts)

7.) Determine the flip-flop input functions and output function(10 pts)

8.) Draw your resulting circuit.(5 pts)

9.) Is your circuit self-correcting? Show how you reached this conclusion.(If yes, do not correct)(10 pts)

10.) Fill in the line for Q in the timing diagrams below, assuming Rising-edge triggered Flip Flops, and all inputs high-active. You may assume Q is initially 0.(10 pts)

11.) The D FF used in the timing diagram below is Rising-edge triggered, has a setup time of 2 ns, and a hold time of 1 ns. The clock period is 8 ns (125MHz clock). Do any of the transitions below have a chance of working incorrectly? Which ones and why?(10pts)

12.) Complete the following timing diagrams, assuming falling-edge triggered flip-flops, all inputs high-active, and Q initially zero.(10 pts)
