Textbook: Signal Processing and Linear Systems, B. P. Lathi, Oxford University Press, ISBN: 0-19-521917-1

Objective: Linear System II is intended to provide students with an introductory, yet comprehensive, treatment of discrete-time systems and signals. The course teaches the theories of Sampling, Frequency Response, Fourier transform, Z-transform, Discrete-time Fourier transform (DtFT), digital filter (FIR and IIR) and Discrete Fourier transform (DFT) which form a foundation for many advanced engineering courses such as Digital Control, Communication, Digital Signal Processing, etc. The course focuses on engineering practice in digital signal processing with many hands-on computer experiments using MATLAB. Students will acquire familiarity and competence in solving both digital signal analysis problems and some digital system design problems using the course material.

Course Schedule:

1^st and 3^rd Week: Introduction to discrete time signals and their mathematical representations (Chapter 5 and 8). Sampling and Typical signal models: u(n), d(n), complex sinusoids, real sinusoids, periodic signals. Sampling of signals, signal correlation, signal components and Fourier series representations of signals (Line spectrum) Homework I and supplemental problems (Due 2^nd class of 2^nd week). Homework II and Supplemental readings and computer problems are due on the 2^nd class of 3^rd week.

1^st Exam: 1^st class of 4^th week

4^th - 6^th (1/2) Week: Discrete-time Fourier Transform (DtFT) and Sampling theory. (Chapter 5 and 10 and supplemental materials) Discrete Fourier transform (DFT) and Spectrum analysis. Homework III and Supplemental readings and computer problems (Due 1^st class of 6^th week).

2^nd Exam: approx. date: 1^st Class of the 7^th week

6^th (1/2) – 10^th Week: Discrete-time systems, frequency response of digital filters and Introduction to Z-transform (Chapter 9, 11, 12). Homework IV and Supplemental readings and computer problems (Due 2^nd class of 7^th week). Homework V and Supplemental readings and computer problems are due on the 2^nd class of 9^th week.

3^rd Exam: 2^nd Class of the 10^th week

Grading policy: Three exams: 30% each; Homework: 10%. *A=90%; B=80%; C=70%; D=60%; If the total score is less than 50%, the final grade will be F.

* *No make-up examination or quiz will be given unless the student has received permission from the instructor prior to the examination or experienced some emergency beyond his/her control. Students are permitted to use a self-prepared (no Xerox copy) hand written study guide during the exams (one 11" by 8.5" sheet both sides).

** *Homework will be graded regularly and the solutions will be available at the front desk of EE Department office or on the Web. Every student is expected to work out all the assignments independently and turn in his/her works as scheduled. Office hours have been set in the following table and the students are encouraged to make use of those to have their academic difficulties resolved. If you can not meet me at the scheduled office hour, you can set up an appointment with me. The instructor is responsible to provide the first exam grade before the 5^th week drop date.
