EE123: Digital Signal Processing
|
|
---|
Spring, 2018!
*** IMPORTANT *** 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.

Tentative Course outline:
A list of the topics that will be covered is given Here, in the order that they will be covered This may change based on time.
Review of discrete-time signals and systems, Discrete-Time Fourier Transform (DTFT), z-Transform (Chapters 2 and 3); digital filter structures (Chapter 6)
Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) (Chapters 8 and 9)
Wavelets
Sampling and quantization, finite word length effects (Chapters 4 and 6)
Frequency response of LTI systems (Chapter 5) and filter design techniques (Chapter 7)
2D signal processing – Tomography
Compressive Sampling
Approximate Grading distribution:
Homework: (Weekly) 15%
Labs: 15%
Midterm 1: 2/23rd, in class + section (25%)
Midterm 2: 4/6th, in class + section (25%)
Project: (20%)
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 Wednesday and due the next Wednesday 11:59pm.
Homework submission will be in digital form through gradescope. Here's a LeTeX 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.Submission is time-stamped!
Homework will be self graded. Self grading is usually part of the following homework which will due at the same time of the following homework. For example, HW1 self-grading will due at the due date of HW2. If the self-grading due date is different from the following homework, we will announce it.
Homework slip policy: the homework with the lowest grade will be dropped
