  1. A. V. Oppenheim and A. S. Willsky with S. H. Nawab, Signals & Systems, 2nd ed., Prentice-Hall, Upper Saddle River, NJ, 1997.
  2. Matlab use is required for this course. The following toolboxes are also required: Symbolic Math, Signal Processing, DSP, Control Systems. You can download a license key and instructions for installing Matlab from the OU IT Store at https://itstore.ou.edu/. Alternatively, you can purchase the Matlab and Simulink Student Suite for $99: http://www.mathworks.com/academia/student_version/ Matlab is also available on the College of Engineering Virtual Lab (see handout on the course web site).


You will submit your Matlab homework projects electronically on Canvas. Announcements will be posted to the course Canvas page. Important information will also be distributed by Canvas notifications. Make sure to configure your Canvas notifications!

The University of Oklahoma is committed to providing reasonable accommodation for all students with disabilities. Students with disabilities who require accommodations in this course are requested to speak with the instructor as early in the semester as possible. Students with disabilities must be registered with the Disability Resource Center prior to receiving accommodations in this course. The Disability Resource Center is located in Goddard Health Center, Suite 166, (405) 325-3852 (Tel) or (405) 325-4173 (TDD only). The Disability Resource Center web site is located at http://www.ou.edu/drc/home.html


It is the policy of the University to excuse absences of students that result from religious observances and to provide without penalty for the rescheduling of examinations and additional required classwork that may fall on religious holidays. It is the responsibility of the student to make alternate arrangements with the instructor at least one week prior to the actual date of the religious holiday.



This page outlines the University's expectations of academic honesty, defines misconduct, provides examples of prohibited conduct, and explains the sanctions available for those found guilty of misconduct. Additional information about the meaning of academic misconduct in this course is provided later in this syllabus.

The UOSA Statement of Academic Integrity will be used in this course.


This course will provide an introduction to the fundamental techniques of analyzing and designing linear time-invariant systems, including elementary topics in control and communications, as well as analog and digital signal processing.


It is CRITICAL that you pace yourself and KEEP UP. Don't put off assignments until the night before they are due. Instead, start each assignment early enough that you can ask questions during office hours if you run into trouble or have questions. This will save you LOTS of time. If you start an assignment the night before it is due and you run into trouble, then you will have to stay up all night trying to figure out the answers to your questions. If you start early, then you can stop when you have problems and ask questions during office hours. This approach will minimize the total number of hours you spend on each assignment.

Try to LEARN DURING CLASS by participating in the lectures, both intellectually and vocally. Try to use your time outside of class to DRILL by working exercises. The homework assignments will be based primarily on the LECTURES. The tests and exam will be based primarily on the HOMEWORK.

If you keep up, then you should be able to understand the lectures and LEARN DURING CLASS. If you don't understand something in a lecture, then you should raise your hand and ASK QUESTIONS such as "I don't understand what you just said. It confuses me because$\ldots$" DO NOT BE ASHAMED OR EMBARRASSED to ask questions!


Homework will be assigned during class. You are encouraged to work together on homework, but DO NOT COPY! Each problem solution that you turn in must be your own; The lowest one-fourth of your homework grades will be dropped. Late homework will not be accepted. Homework solutions will be posted on the course web page.

Working the homework problems on time will help YOU to do well on the tests and exam.


There will be special homework projects that will require the use of MATLAB. These will be graded separately from the regular homework.

NOTE: none of your Matlab project grades will be dropped.

The standards of academic honesty articulated above for homework apply to Matlab projects as well. In addition:

  1. All computer codes and results that you turn in as solutions must be your own original work, except as noted in (4) below.
  2. If you obtain code from another person in an electronic format and incorporate it into the solution that you turn in, then you are guilty of academic misconduct.
  3. If you obtain code from another person in electronic or hardcopy format, type some or all of it in yourself, and then include this as part of the solution that you turn in, then you are guilty of academic misconduct.
  4. In certain cases, it may be acceptable to incorporate existing public domain and/or library computer algorithms and codes into a solution that you submit. In such cases, however, you must always obtain prior authorization from the instructor and you must always document the source of any algorithms and/or code that are not your own original work.


"Paper and pencil" homework assignments will be due at the start of class on the published due date. Matlab homework assignments will be submitted electronically on Canvas and will generally be due at midnight on the published due date. Late homework will not be accepted.

There are two reasons for this policy. First, accepting a late homework assignment from one student is unfair to other students who may have stayed up all night to get the assignment done and may also have sacrificed grades in other classes to get it done. Second, it would be detrimental to the overall learning outcomes of the class to delay the posting of homework solutions in order to accommodate late assignments.

If you cannot attend class on the day that a "paper and pencil" homework assignment is due, then you can either:


There will be two tests and a cumulative final exam. Calculators will NOT be allowed on the tests and final exam.

The two tests will be given in the evening (outside of the regularly scheduled class meeting time). This helps you because you will have extra time to work the test if you need it - up to three hours total. More than 15 years of experience has shown that this policy improves student test scores, learning, outcomes, and satisfaction. The date and time of each test will be chosen by the class to not conflict with tests, exams, and major projects in other courses. Should you have a legitimate conflict with the chosen test time, see the instructor as soon as possible so that an alternate time can be arranged.

In case a consensus can not be reached concerning an acceptable date and time for a test, then that test will be held during the regularly scheduled class meeting time.

The official date and time for each test will be announced in class at least one week in advance.

The tests and the exam are CLOSED BOOK and CLOSED NOTES. Formula sheets will be provided with each test and exam. These formula sheets are available on the course web page under ``handouts."

Makeup tests will not be given. If you miss a test and your absence is NOT officially excused, then you will receive a zero grade for that test. If you miss a test and your absence IS officially excused, then your final exam grade will be used in place of the missed test grade.


Your final average will be calculated as shown in the table below.

What Value
Homework, best three-fourths 10%
Matlab homework projects 10%
Test One 25%
Test Two 25%
Final Exam 30%

These numerical grades will be converted into letter grades using a curve that will be determined by the instructor. The same curve will be applied to everyone in the class. The curve will never hurt you relative to the standard ten-point grading scale.
