ELEC 320, Fall 1998
Prof. Rich Kozick

Homework 7

Date Assigned: Wednesday, September 16, 1998
Date Due: Friday, September 18, 1998

  1. We will continue to work on Lab 1 for one more week (through Tuesday, September 22). Then individual lab reports will be due at 9 AM on Monday, September 28. I would strongly suggest that you submit a rough draft of your report next week so that I can give you some feedback. Guidelines for the lab report are listed on the Lab 1 assignment sheet, but you should present your filter designs, analyze the frequency response (including the derivation of the cutoff frequency), and present your measured data on Bode plots. Your report should discuss how well you achieved each filter specification. That is, you should compare the measured gains and cutoff frequencies with the specified values.

  2. Please submit solutions to items 1 and 3 from Homework 6 on Friday.

  3. Please solve problem 1.34 in the text using MATLAB. Plotting discrete-time signals with the stem command is discussed in Section 1.3 of the text. A sample MATLAB program that solves part (a) of problem 1.34 is available at http://www.eg.bucknell.edu/~kozick/elec32098/hw7s.m.

    Rather than submitting your program on paper, please send it to me by email. (If the file is named foo.m, the it can be sent to me via email by typing mail kozick < foo.m at the UNIX prompt.) I will then run your program in my account and view the plots. Try to do all of the work in one or two ".m" files. A plot can be produced in a second window using the command figure(2) before the plot or stem command. A third plot can be created in a new window using figure(3), etc.

    Please submit your answers to the questions in the text on paper. There is no need to print any of the plots produced by your program.

  4. Continue reading Chapter 2, Sections 2.1, 2.2, and 2.3.

Thank you.
