ECE 320 Signals and Systems II. Spring 2014 Monday and Wednesday, 12.00 – 1.15 pm. University Hall 1201 Instructor: Prof. Janos Gertler, Engg. 3211,
[email protected] Office hours: M, W 3.00 – 4.00 Teaching Assistant: TBA Textbooks: 1. Oppenheim and Willsky: Signals and Systems, Second Edition, Prentice Hall. (Required) 2. Buck, Daniel and Singer: Computer Explorations in Signals and Systems Using MATLAB, Second Edition, Prentice Hall. (Recommended) Course description. The course is a continuation of ECE 220. In addition to reinforcing the basic understanding obtained in the first course, 320 is concentrating on the frequency characterization of signals and systems and introduces the discrete-time counterparts of the continuous-time concepts. Subjects: 1. Review of fundamentals of signals and systems 2. Discrete-time linear time-invariant systems 3. Fourier series, continuous and discrete time 4. Review of continuous-time Fourier transform 5. Discrete-time Fourier transform 6. Discrete-time filtering 7. Sampling and reconstruction 8. z-transformation Work requirements: Paper and pencil homework will be assigned every week There will be 2 MATLAB projects, to be performed in groups, and an individual reading assignment There will be three exams (midterm and final), all in-class, closed book.
Course grade: 3 exams 20% each 2 projects plus reading assignment 10% each homework 10% total During the final exam period, the first or second exam may be re-taken. The score will be multiplied by 0.85 and, if higher than the original score, will replace it. Week-by-week schedule (tentative) Part I. Jan. 22. Signal energy and power. Signal manipulations.
