  1. Draw ASM diagram here (20 pts) 21. (15 pts)

AB CD 00 01 11 10

Y =

  1. (5 points) In the LEFT image, what is the period of the signal on the top?

a) About 250 μs b) About 500 μs c) About 1 ms d) About 100 mV e) None of the above are within ±5% of the correct value

  1. (5 points) In the LEFT image, what is the duty cycle of the signal on the bottom?

a) About 25% b) About 50% c) About 250 μs d) About 500 μs e) None of the above are within ±5% of the correct value

  1. (5 points) In the RIGHT image above, what is the rise time of the signal on channel 2?

a) About 35 ns b) About 25 ns c) About 500 μs d) About 2.16 V e) Unknown, since it is impossible to tell which signal is on channel 2.

  1. (5 points) In the RIGHT image above, what is the propagation delay from the first rising edge to the second rising edge? a) About 35 ns b) About 25 ns c) About 500 μs d) Impossible to say, since the two signals have different vertical scales e) Impossible to say, since the two signals have different time bases
  1. (5 points) Look at the oscilloscope traces on the right (on the top of the previous page) one more time. You may be able to tell how the scope was triggered to get this capture, but ignore the EXACT method used here, and indicate which of the following would have resulted in a usable capture showing the two rising edges. (Select ALL that would have produced a capture suitable for the propagation delay measurement, assuming that other scope settings like position, vertical scale, horizontal scale, etc. were correct.) a) Set trigger level to about 2.5 V, rising edge, triggering on Channel 1 b) Set trigger level to about 2.5 V, falling edge, triggering on Channel 1 c) Set trigger level to about 2.5 V, rising edge, triggering on Channel 2 d) Set trigger level to about 2.5 V, falling edge, triggering on Channel 2 e) Set trigger level to about 5.0 V, rising edge, triggering on Channel 1
  2. (5 points) One of the slides from this semester’s train problem is shown above. After Train A goes back to S4, what is it supposed to do next, according to the train assignment given? a) Continue traveling through Track 2 to S b) Continue traveling through Track 2 to S c) Wait at S4 until Train B clears Track 3 d) Wait at S4 until Train B backs up onto Track 2 e) None of the above
  3. (5 points) Which of the following stances or gestures was recommended by Michael Laughter as being effective for presentations? a) The “fig leaf” b) The “weatherman”

If Train A is

between S4 and

S5 when Train B

arrives at S2, then

Train A must go

back to S4 while

Train B waits.

  1. (5 points) What would be the value of IO_DATA at t=57 ms? (all numbers given as hexadecimal) a) High impedance (ZZZZ) b) 0000 c) 00E d) 001F e) FFE
  2. (20 points) The ASM diagram above is the one from the lab manual and slides, showing a state machine with one input X, and one output Z, where the output is asserted if and only if the two most recent values of X have been 1. Using this same concept of a sequence-detecting state machine, draw the ASM diagram for a state machine that asserts its output Z if and only if the two most recent values of X have been 0, followed by 1. There is no need to number the states, but you must name them, you must indicate the Start state, and you must show what happens for every possible value of the input X. For full credit, use the minimum number of states.
  3. (15 points) Solve the Karnaugh map on the answer sheet, producing a minimal sum of products expression, by
    • Circling the correct, minimal set of prime implicants on the diagram (10 points)
    • Writing the reduced expression where indicated below the diagram (5 points)
