COURSE DESCRIPTION: Analysis techniques for signals and systems. Signal
representation, including Fourier and Laplace transforms. System definitions and
properties. Use of convolution, transfer functions, and frequency response to determine
system response. Applications to circuit analysis. Prerequisites: ECE 2004 (C- or above),
Network Analysis and Math 2214, Intro. Differential Equations.

Homework:
Homework will be assigned in class. All homework is due at the beginning of class one
week later on the following week. Late homework will not be accepted. Homework
problems must be worked on standard 8 1/2 x 11 papers with all problems neatly worked
and answers clearly designated. Pages should be stapled together in the upper left-hand
corner and turned in without being folded. HOMEWORK NOT COMPLYING WILL
BE RETURNED UNGRADED.
Examination: No calculators will be allowed during exams. All grading are final.
However, grading errors will be cheerfully corrected. If you have any questions about
your progress and standing in the course, don't hesitate to ask your instructor during his
office hours.
Homework and exam solutions:
Internet will be used to distribute homework and exam solutions. The web address for the

Honor system:
You may work together on homework. However, each student must submit an
individual and independent homework solution. The GTA will check for
copying/cheating. Students are advised to visit the following Website for information
regarding Honor System:
