EE123: Digital Signal Processing

chirp

Fall, 2012

Course Description

Catalog Description: (4 units) Discrete time signals and systems: Fourier and Z transforms, DFT, 2-dimensional versions. Digital signal processing topics: flow graphs, realizations, FFT, quantization effects, linear prediction. Digital filter design methods: windowing, frequency sampling, S-to-Z methods, frequency-transformation methods, optimization methods, 2-dimensional filter design.

Prerequisites: EECS 120, or instructor permission.

Course objectives: To develop skills for analyzing and synthesizing algorithms and systems that process discrete time signals, with emphasis on realization and implementation.

Why should you care? Digital signal processing is one of the most important and useful tools an electrical engineer could have. It impacts all modern aspects of life and sciences; from communication, entertainment to health and economics.

New This Year - Software Defined Radio Labs and Project


Last February, a V4L/DVB kernel developer Antii Palosaari discovered that DVB-T dongles based on the Realtek RTL2832U can be used as cheap Sodtware Defined Radios (SDR). Basically the chip allows the transfer of raw samples to a host computer. The samples can then be used to digitally demodulate and process almost anything that is transmitted between 64-1700Mhz!

Several homeworks/Labs will use the SDR. Each student in the class will receive a dongle and will be able to experiment with its capabilities. The final project will also be based on SDR. Several possibilities are writing an FM receiver, digital radio receiver, Police scanner, GPS receiver, NOAA weather alert receiver or satelite imagery and more.

Homework Instruction:

  • Weekly assignments consisting of problem sets. In addition there will be about 4-6 laboratories consisting of Matlab programming.

  • Students can use GNU Octave for the Matlab assignmets.

  • Homework will be assigned each Thursday and due the next Thursday 11:59pm.

  • Homework submission will be in digital form through b-space. Filename convention is FirstName_LastName_HW01_sol.pdf. You are encouraged to typeset the homework. Here's a mbox{LaTeX} template Miki_Lustig_hw01_sol.tex that produces this output after compilation. Scanners are available in the instructional lab.

  • No late hw without prior concent from the instructor. B-space submission is time-stamped!

Project:

  • Slow-Scan TV (SSTV) over FM radio project page
