Due: 01/20/2011
Need a solution?

Homework #3

Chapter 6: 18 (a) and (b), 20, 23, 27, 28, 32 (a)
Due: 01/27/2011
Need a solution?

Homework #4

Chapter 4: 12, 20
Chapter 6: 18(c) (plot II-type block diagram with integrators), 22(a)-(b)
Chapter 15: 33(b)-(c), 39(a), 43
Additional items:
Problem 39 (a): Use matlab to compute and plot the response of the system. You should use commands like 'tf', and 'step'.
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.
