2. Consider the negative unity feedback system shown below, where the plant has the following transfer function: 1 G(s) = s R(s) + E(s) Y(s) C(s) G(s) The specifications of the closed-loop system are: Spec1: the closed-loop system is stable, Spec2: no overshoot for unit step input r(t) = u(t). Spec3: %2 settling time should be between 1 and 2 seconds for unit step input r(t) = u(t). Spec4: zero steady-state error lim e(t) for unit ramp input r(t) = tu(t) (a) Draw the allowable region of the closed-loop pole locations to meet the specifications Spec2 and Spec3. (b) Now consider to design a controller C(s) = $c_p + \frac{c_i}{s}$ to satisfy all the specifications. This controller is called PI controller (Proportional plus Integration parts). i. Explain the reason why any PI controller C(s) = $c_p + \frac{c_i}{s}$ ($c_p > 0$ and $c_i > 0$) satisfies both Spec1 and Spec4. ii. Set $c_i = 9$. Draw the root locus which shows how the closed-loop poles move when the parameter $c_p$ is increased from zero to infinity. iii. For $c_i = 9$, select a value of $c_p$ so that the closed-loop system satisfies all the specifications mentioned above. Write your answer here.

You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner (leasing is a very common practice with expensive, high-tech equipment). The scanner costs $6,000,000, and it would be depreciated straight-line to zero over five years. Because of radiation contamination, it actually will be completely valueless in five years. You can borrow at 7 percent before taxes. Your company does not anticipate paying taxes for the next several years, but the leasing company has a tax rate of 25 percent. Over what range of lease payments will the lease be profitable for both parties? (Do not round Intermediate calculations. Enter your answers from lowest to highest rounded to 2 decimal places, e.g., 32.16.) ? Answer is not complete. Total payment range $ 1,460,586.53 to

3.12 Consider an 8-bit bit-parallel ALU with only four functions: add, subtract, and bit- wised AND and XOR. Assume an adder/subtractor module uses a hybrid adder de- signed from CLA(2) modules. In addition, the overflow flag must be masked out when performing bitwise computation. Assume only 8-bit, 2-to-1 MUXs are available. Do the following: a. Draw the data path and estimate its propagation delay assuming 0.1 ns delay for each NOT and NAND gate. b. Construct the truth table for its Map module. 5.28. A serial adder inputs 2-bits x and y and outputs their sum-bit s every clock cycle. It keeps the presence or the absence of a carryout bit internally. Assuming that the initial carry-in is zero, do the following: a. Draw a Mealy FSD for the serial adder. b. Design the Mealy serial adder FSM. c. Draw a Moore FSD for the serial adder. d. Design the Moore serial adder FSM. e. Design a fault-tolerant Mealy serial adder.
