Course Description: This course is an introduction to the fundamentals of modern communications theory.
Course Objectives:
For your convenience a detailed list of topics and suggested homework problems is available.
Laboratories: This course is part of the "Integrating Mathematica into the electrical engineering curriculum" project. Included are a series of Mathematica notebooks. Students will be expected to use Mathematica to solve problems in class, as well as in take-home assignments and projects.
Prerequisites: ELE314 or equivalent. Lecture 3 hrs. 3 cr.
Textbook: "Modern Digital and Analog Communication Systems," by B.P. Lathi, Oxford University Press, Third Edition, 1998.

Grading policy: The final grade will be based on the results of three
mid-semester exams, a final exam and homework problems. The following tentative weighting
schedule will be used: exams 45%, final 30%, and homework problems 25%.
