Expected Student Outcomes:

A student who has successfully completed this course should be able to:

1. Classify systems based on properties of their input-output relationship.
2. Analyze and synthesize signals using the definitions and properties of the Fourier series and Fourier transform.
3. Apply convolution, Fourier series, and Fourier transform methods to determine the output of linear time-invariant systems.
4. Analyze simple modulation systems and filters, and understand their applications.
5. Define a random experiment, its outcomes, its events, and the allowable probability distributions for it.
6. Apply independence of events, conditional probability, and Bayes rule.
7. Calculate the probability of an event for a random variable given its cumulative distribution function or probability density function.
8. Determine the mean, variance, and standard deviation of a random variable.
9. Determine the autocorrelation and power spectral density of a random signal.
10. Characterize LTI system response to random signal.

Text: Linear Systems and Signals, by B.P. Lathi, Berkeley-Cambridge Press, 1992

Probability, Random Variables, and Random Signal Principles, 3rd edition, by P. Z. Peebles, McGraw Hill, 1993

(optional) Mastering Matlab, by D. Hanselman, and B. Littlefield, 1996

10 quizzes for 70%

1 final exam (signals and systems) for 15%

1 final exam (probability) for 15%

• The letter grade assignment is based on the following scale: from 100 to 90 pts. => A, from 89 to 80 pts. => B, from 79 to 70 pts => C, from 69 to 60 pts. => D, from 59 to 0 pts. => E.
• Homework will be assigned but not graded. The effort spent in doing homework problems will be reflected in the quiz and test performance.
• Quizzes will test for mastery of material required for the homework problems. Quizzes on specific material can be given any time after the expected completion data for the homework assignment. A typical quiz will last 10 to 15 minutes. Quizzes that require computer software will be take-home quizzes.
• Failure to take a quiz or exam during the assigned class period will result in a grade of zero for that test. Make-up exams will be given in cases where the student contacts the instructor prior to the exam and receives permission to make the test up.
• The student is responsible for all business conducted during any scheduled class period. Any revision to the test dates, homework assignments, etc. will be made during the class period.
• The detected use of unethical tactics on a quiz or test will result in a zero for that quiz or test.
• The lectures will follow the text. The student is expected to read the text and is responsible for all material in the reading assignments. The sections of the text should be read prior to the class meeting where its material will be covered.
• The student is expected to be familiar computer math packages such as Matlab, Maple, MathCad, or Mathematica. Matlab will be used for computer quizzes, examples, and homework problems. Students should sign up for computer accounts in the Engineering Workstation Laboratory (EWL) to have access to Matlab.
• The key to doing well with the given point distribution is consistent hard work. Plan on at least 6 to 12 hours weekly for homework and study (outside of class time).
