EE123: Digital Signal Processing

chirp

Spring, 2016

*** NEW *** If you wish to earn credit for ham radio licensing, consider taking EE198-13 Quick intro to Amateur Radio

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.

Continued from last year - HAM radio and Software Defined Radio Labs and Project


It was discovered by Eric Fry that DVB-T dongles based on the Realtek RTL2832U can be used as cheap Software 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 27-1700Mhz!

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.

In addition, each student will get a Baofeng UV-5r hand held radio. This will be used in Labs and the final project in the class. Every student in the class will take a HAM radio licensing exam, and be licensed by the FCC to operate the radios.

Homework Instruction:

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

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

  • Homework submission will be in digital form through b-courses. Filename convention is FirstName_LastName_HW01_sol.pdf and FirstName_LastName_LAB00_sol.ipynb. 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 consent from the instructor. b-courses submission is time-stamped!
