- Homework #3 (due 1/28/11) [from Chapter 6]: 18(a)-(b), 20, 23, 27, 28, 32(a). Solutions here
-
Homework #4 (due 2/7/11) [from
Chapter 4]: 12, 20; [from Chapter
6]: 18(c) (plot II-type block
diagram with integrators),
22(a)-(b);
[from
Chapter 15]: 33(b)-(c), 39(a),
43. Solutions here
Additional items:
Problem 39 (a): Use matlab to compute and plot the response of the system. You can use commands like 'tf', 'step', 'ss' and 'initial'.
Problem 43: For a fixed value of K that makes the system stable, use the matlab commands 'tf' and 'feedback' to compute the transfer function from x to y. Use 'impulse' to plot the impulse response of the resulting system. - Homework #5 (due 2/11/11) [from Chapter 8]: 22, 23, 30, 32; [from Chapter 12]: 32(b)-(c) (use matlab to plot the frequency response: specifically, commands like 'tf' and 'bode'). Solutions here
- Homework #6 (due 2/18/11) [from Chapter 10]: 33, 34(b)-(c), 39, 47, 48, 49. Solutions here
- Homework #7 (due 2/28/11) [from Chapter 12]: 25 (use 0.002 instead of 0.02 in the impulse train), 31, 40 (enough to provide the transfer function, no circuit design necessary), 42, 47. Solutions here
- Homework #8 (due 3/4/11) [from Chapter 14]: 25, 32 (a)-(b), 34, 39, 44. Solutions here

Grades
The formula to compute the grade is
    grade = max(0.2 * homework + 0.3 * midterm
+ 0.3 * final exam + 0.2* project, 0.6 * final exam + 0.4* project)
Even if you count on getting the overall grade with only the final
exam and the final project, you should still turn in all your
homework. Past experiences reveal that it is nearly impossible to
get a good grade without having done the homework.
You can check your grade online via WebCT. Please check it out regularly to make sure your homework is being graded/transcribed correctly!
