Syllabus: EE 448
Digital Signal Processing

SEMESTER: Spring 2001

CREDIT HOURS: 3.0

CLASS TIMES
(sequence # 37551): Monday, Wednesday, and Friday, 12:40-1:30, room 329

REQUIRED TEXT: "Digital Signal Processing: Principles, Algorithms, and Applications," John G. Proakis and Dimitris G. Manolakis, 3rd ed., Prentice Hall, 1996, ISBN 0-13-373762-4.

Lectures will frequently include material not found in the textbook. You are responsible for all material discussed in class, assigned in the text, or covered in lab.

USEFUL REFERENCES:
"Discrete-Time Signal Processing", Oppenheim & Schafer, 2nd ed., Prentice Hall, 1999.
"First Principles of Discrete Systems and Digital Signal Processing", Strum & Kirk, Addison Wesley, 1989.
"A Course in Digital Signal Processing", Porat, Wiley, 1997.

Also, NAU's Cline Library has a number of useful books on digital signal processing.

COURSE PREREQUISITES:
EGR 325 (Engineering Analysis II) with a grade of C or better.

COURSE DESCRIPTION:
Characteristics of discrete time systems, Z and discrete Fourier transforms, and digital filtering and processing techniques.

COURSE GOAL:
To achieve a good introductory understanding of the theoretical fundamentals and practical issues involved in discrete-time signal processing.

TOPICS AND OBJECTIVES (E = Exposure, U = Utility, M = Mastery)

Signals and systems basics U
Sampling theorem M
Quantization E
Difference equations M
Z-transform M
DTFT (discrete-time Fourier transform) U
DFT (discrete Fourier transform) M
FFT (fast Fourier transform) E
FIR filter design U
IIR filter design U
A/D and D/A converters E


COURSE GRADING:
The course grade will be based upon three mid-term exams, homework, quizzes, and a comprehensive final exam. Grades will be based not only on technical content but also on presenting your homework and lab reports in a well organized, neat, clear, professional manner using standard technical terms and symbols.

Exam 1 100 points @ approx. the 5th week
Exam 2 100 @ approx. the 9th week
Exam 3 100 @ approx. the 13th week
Final Exam 150 during finals week
Homework 100  
Quizzes 50 10 points each, only your best five scores count
Total 600  

Final grades will be determined by the following percentages:
A = 90+, B = 80-89, C = 70-79, D = 60-69, F = below 60

At the instructor's discretion, grading thresholds may be relaxed slightly.

Assignments are not accepted late. No makeup exams will be given except by prior arrangement in exceptional, unavoidable, emergency situations. Please contact me immediately if such a situation arises.

QUIZZES:
During at least 6 regular class periods throughout the semester, a short quiz will be given. These quizzes are worth 10 points each, but only your 5 highest quiz scores will count toward your final grade. The remainder will be dropped. Quizzes will not be announced in advance. Also, they may occur anytime during the class period: beginning, middle, or end. If you are not present when a quiz is given, you will receive a zero for that quiz. No make-up quizzes will be allowed under any circumstances. Suggested strategy: keep current and be ready.

ACADEMIC DISHONESTY:
Incidents of cheating or plagiarism are treated quite seriously. The NAU policy on academic dishonesty in Appendix G of the 1998-2000 Student Handbook will apply.

NEED EXTRA HELP?
I want you to succeed in this course! I'm willing to help you in any reasonable way I can. If you're beginning to have difficulty, please contact me before the situation deteriorates.

STANDARD UNIVERSITY POLICIES also apply:
· Safe Environment
· Students with Disabilities
· Accommodation of Religious Observance and Practice
· Institutional Review Board (use of human subjects)
· Classroom Management
· Academic Integrity
· Evacuation
