Date Assigned: Monday, September 14, 1998
Date Due: Wednesday, September 16, 1998

  1. Please do problems 1.27 and 1.28 (parts c, f, g, and h) in the Kamen/Heck text.

  2. Please review Section 1 of the MATLAB Tutorial that accompanies the Kamen/Heck text. Recall that other tutorials on the Suns and MATLAB are available on the Web.

  3. Please study the discrete-time system example of a bank loan described on pages 31-34 of the text. Run the MATLAB program listed in Figure 1.29 of the text, which is available at the URL http://www.eg.bucknell.edu/~kozick/elec320/heck/fig1_29.m

    To run the program on the Sun computers, save the program with filename fig1_29.m in your account. Then start MATLAB by typing matlab at the UNIX prompt. When MATLAB is running, the prompt is >> . To run the bank loan program, type fig1_29 at the MATLAB prompt. This will execute each statement in the file fig1_29.m. Please study the MATLAB program, and try to understand the syntax and what each statement does. MATLAB is also available on the PCs and MACs in Dana. A similar procedure can be used to run the program on those platforms.

    Use the MATLAB program fig1_29.m to answer the following question. How many months would be required to repay a car loan of $15,000 with an annual interest rate of 7.5% when the monthly payment is $300?

  4. Please read Chapter 2, Sections 2.1 and 2.2.
