Unformatted text preview: 18.03 Problem Set 9a Spring 2009 Due with 9b in Room 2106 at 12:55 pm, Friday, May 1 As usual, Part 9a covers material you are responsible for on Exam 3. Part A 1. Lec 28, Wed April 15: Weight and Transfer functions; Convolution. Read: CG. (this time, whole section, including the Laplace transform) Work: 3D1; 2H1; CG p2 do the “easy” exercise in next to last sentence. 2. Lec 29, Fri April 17: Pole diagrams. Read: Lecture Notes. Part B 0. (at due date) Write the names of any person, web site, or materials you consulted. Write “No C” (no consultation) on your paper if you consulted no outside materials/people. 1. Lec 28, Wed April 15: Complex coverup method. To find L 1 parenleftbigg 1 s ( s 2 6 s + 13) parenrightbigg note that s 2 6 s + 13 = ( s 3) 2 + 4 with roots s = 3 ± 2 i . One can then solve for A , B and C in 1 s ( s 2 6 s + 13) = A s + B ( s 3) + C ( s 3) 2 + 2 2 The ordinary coverup method yields (with s = 0) 1 13 = A Next, we justify the complex coverup method. Multiply by s 2 6 s + 13: 1 s = A s ( s 2 6 s + 13) + ( B ( s 3) + C...
