ENEE 473 Analog and Digital Communications
(3)
Required course for majors in the electrical specialty.
Catalog Description:
Definitions and basic
concepts of analog and digital modulation techniques. Fourier series and transform
techniques used to study transmission of signals through linear filters,
time-bandwidth relationships. Amplitude, frequency, and pulse modulation
techniques described and analyzed. Periodic sampling and the
Nyquist sampling criterion. Fall semester. Lecture 4 hours.
Prerequisites:
ENGR 222 and ENEE 373 with
grades of C or better.
Textbook/references:
Introduction to Communication Systems by Ferrel Stremler, 3rd
edition.
Course Objectives: (numbers in brackets
indicate the relationship to engineering program outcomes)
Goal: to
cover both analog and digital communications methods, modulation, and
transmission, to prepare students either for jobs relating to communications or
for graduate school. (1,2,5,6,7)
Class/Laboratory Schedule:
Lecture either three times per week at 50 minutes
per class, or two times per week at 75 minutes per class.
Topics Covered:
The amount of material we cover in the course will,
to some extent, depend on the background of the class, and the amount of background
material that we must cover. In order to
cover all of the material that is absolutely necessary (including the
applications of probability and statistics required by ABET of EE's), the
material will covered in a different order that that in your book. Specifically, I plan to cover:
