Philosophy

Digital signal processing and its applications are of interest to a wide variety of scientists and engineers. The course covers such topics as characterization of linear discrete-time circuits by unit-pulse response, transfer functions, and difference equations, use of z-transforms and Fourier analysis, discrete Fourier transform and fast algorithms (FFT), design of finite and infinite impulse response filters, frequency transformations, study of least squares filters for deterministic and stochastic inputs.

Topics

(1) Discrete time signals and systems;(2) Review of z-Transforms and Difference Equations; (3) Sampling of continuous signals;(4) Transform analysis of linear-time invariant systems; (5) Introduction to Digital Filters; (6) Digital Filter Realization and Implementation; (7) Finite Impulse Response Filters; (8) Infinite Impulse Response Filters; (9) The Discrete Fourier Transform

Exams

The first midterm will take place on February 29, 2008 from 6:00 to 8:00PM in 1B28 (in the same hallway as the ECE main office, on the other side). A review session will take place on February 25 in class. Please download the problems here

The second midterm will take place from 5:00 PM to 7:00 PM on April 18 in classroom 1B28. A review session will take place on April 14 in class. Please download the problems here

The final exam will take place on from until in the classroom where we usually meet. The final will be open notes and open official class textbook. The final will include all the topics covered in class during the semester for which homework has been assigned and graded.

The last week of class will be devoted to review sessions. Please download the review problems here

Policies
Homework is due on Fridays at the beginning of class.
Assignments must be neat,corganized and legible. In plain English: If we cannot read your assignment, you will not get credit for it. Typed assignments are welcome.
At the start of each problem, write out a brief description of the problem including given information and what is to be found. Put a box around all final answers.
Show your work enough to fully demonstrate your understating and your arrival at your answer.
Write on only one side of the paper. Pages must stapled be in order (i.e. following the order in which the problems were assigned).

You should go over your homework as soon as it has been graded and returned to you. Once an assignment has been returned to you, you only have TWO WEEKS from the return date to question the grading. Questions regarding the material are always welcome.
