ELEC 320, Fall 1997

Homework 1

Date Assigned: Wednesday, August 25, 1997
Date Due: Friday, August 27 and Week of September 1, 1997

  1. Please review your notes from EE 102 and EE 209. In particular, review the concepts of phasors and impedance for circuits that contain capacitors, inductors, and resistors. Also review operational amplifiers and "frequency response" of filters.

  2. Please review complex numbers in Appendix A of the Kamen/Heck text. Appendix A provides a brief summary of the important formulas for complex number arithmetic. You might want to consult your EE 209 circuits textbook (or any other book that you like) for a more thorough review of complex numbers.

  3. Please review pages 667-670 in Appendix B of the Kamen/Heck text. These pages review vectors, matrices, and the operations of matrix addition and multiplication. Vectors and matrices are the key elements in the software package MATLAB, which is extremely useful and popular for linear systems, signal processing, and computation.

  4. Please read Section 1 (pages 1-7) of the "MATLAB Tutorial". A paper copy of this tutorial will be distributed in class. Electronic versions are available at tutorial.doc (Word for Windows vers. 6.0) and tutorial.wp (Wordperfect 5.1 for DOS).

    A MATLAB tutorial developed at Bucknell University is available at
    This tutorial is Chapter 4 from a more complete set of documentation on computing at Bucknell University that you can access at
    For general information about the Sun computing environment at Bucknell, useful documentation is available at, which can also be purchased in paper form at the bookstore.

  5. Please work on designing the low-pass, high-pass, and band-pass filters specified on the Laboratory 1 assignment. Note that there are many different circuits that can satisfy the design specifications. Take your time, ask plenty of questions, and try to understand the fundamental concepts.
Thank you.
