Textbook:
Signal Processing First, J. H. McClellan, R. W. Schafer, and M. A. Yoder, Pearson/Prentice Hall, 2003.
The compulsory textbook is an essential resource. You are responsible for reading and studying everything in the course textbook, unless it is explicitly stated that a section is omitted. Omitted sections are listed on the course web page. The required textbook is self-sufficient for this course. However for those who want to go beyond and learn the subject at a more advanced and sophisticated level, the following may be recommended:
Signals and Systems, Alan V. Oppenheim, Alan S. Willsky, with S. Hamid Nawab, Pearson New International Edition, 2/E, 2014.
This is a classic and widely known textbook currently used in the EE department.

Topics:
Week 1: overview of the course, sinusoidal signals and their parameters, complex exponential signals and phasor representation
Week 2: time domain vs frequency domain, frequency spectrum representation of signals
Week 3: Fourier series representation of periodic signals
Week 4: quantization, discrete-time sequences, sampling, oversampling, undersampling, Shannon/Nyquist sampling theorem
Week 5: Nyquist rate, folding frequencies, reconstruction, aliasing
Week 6: discrete-time sequences, digital computation, causality, finite impulse response (FIR) filters
Week 7: linearity, time-invariance, linear time-invariant (LTI) systems, discrete-time convolution sum (1D, 2D, 3D)
Week 8: frequency response of finite impulse response (FIR) filters
Week 9: z-transformation
Week 10: infinite impulse response (IIR) filters, 1st- and 2nd-order systems, pole-zero diagrams
Week 11: continuous-time systems, linearity, time invariance, and causality revisited, convolution integral for continuous-time systems, stability of systems
Week 12: frequency response of continuous-time systems
Week 13: continuous-time Fourier transform
Week 14: continuous-time Fourier transform pairs and properties
Week 15: Final Exams

Examinations and Grading:

Exams will be closed book and notes. Necessary formulas will be provided. Calculators will NOT be needed.

Midterm Exam (35%):
Date: 24 March 2025, Monday
Time: 18:00-20:00
Rooms: EE-412 and EE-517


Final Exam (40%):

Date: 29 May 2025, Thursday
Time: 18:00-20:00
Rooms: EE-412 and EE-517

Mini Projects (15%):
Two MATLAB Assignments (7.5% each) in the nature of small projects.

Homework (10%):
Two analytical problem sets (5% each) and suggested problems from the textbook (no credit).

We do not accept projects/homework sent through e-mail. We take off 25 points for each day projects/homework are turned in late. We do not accept late submission 48 hours after the due date. Therefore, you may turn in projects/homework on the due date, the day after, and the day after that. All assignments should be submitted on Moodle as a single pdf file.

You should submit the results of your own work as homework. Borrowing full or partial results and/or code from your peers or elsewhere is prohibited and will be punished. If plagiarism is detected in submitted homework or projects, you will not be able to submit any further homework/project and get a homework/project grade of zero for the course. Disciplinary action may be taken.

There will be a two-hour MATLAB tutorial and some face-to-face problem-solving sessions (two hours each) during the semester.

Minimum Requirements to Qualify for the Final Exam:


• To attend the midterm exam and get a grade >=30.

There will be a make-up exam during the last week of classes that will cover all the topics. You may take the make-up exam if you have a medical report or special permission on the day of the Midterm Exam. Missed homework deadlines cannot be made up for. We only accept medical reports or special permissions that are approved by the Dean's Office (Please do NOT bring us a copy of your medical report or special permission as they are sent to us through the Dean's Office.).
