HW Assignments & Solutions
There is not a 1-to-1 correspondence between "Notes #" and "Lecture #", so...
Suggestion: Print out all notes for a chapter **before** we begin that chapter and bring them to each class.
Review of Complex Numbers and Sinusoids (You are responsible to review this material... you will be tested on this)
Finding Differential Equations
DT Convolution Examples
CT Convolution Practice
Videos of Convolution Examples and Web Demos
Chapter 3: Fourier Series & Fourier Transform for CT Signals
Historical Link: Fourier on Wikipedia
Fourier Series Examples
Fourier Transform Examples
Chapter 5: Zero-State Solution via Frequency Domain Methods
Frequency Response Examples
Chapter 4: DT Fourier Methods
Chapter 6: Laplace Transform for CT Signals
Historical Link: Oliver Heaviside on Wikipedia (Heaviside championed use of Laplace in Circuit Analysis)
Historical Link: Laplace on Wikipedia
(Note the statement that it was really Euler who invented the Laplace Transform!)
Chapter 8: CT System Analysis using Laplace Transform
Bode Plot Examples
Some Real-World Analyses Using LT & Bode Plots
Chapter 7: Z Transform and DT System Analysis
We will be using MATLAB during EECE 301 for demos and assignments.
There will be a Tutorial during an early Discussion section to get you started with MATLAB
(See the link to my MATLAB Tutorial above in the section "Discussion Notes" ).
Here are some other tutorial links you might find useful:
A. Learning Links
Textbook's Web Page
Has the following things:
Worked Problems for more practice
Downloadable M-Files from the book
Graphical Demo of Complex Sinusoid (Rotating Phasor)
Signals & Systems Demos (Johns Hopkins University)
A site of java applets to demonstrate signals & systems ideas.
Great Web Site for Bode Plots
The Scientist and Engineer's Guide to Digital Signal Processing
A book mostly about digital signal processing (as in EECE 402) but could be helpful for EECE 301
And... it is completely free to download!!!
B. Connections to the Real World
Info on DSP Processors
Dedicated H/W D-T System
Analog Devices DSP Site
Analog Devices manufactures DSP chips, ADC, digital receiver chips, etc. This is a good place to see how the theory we cover gets put to use.
Graychip's DSP Chip Site
Graychip manufactures DSP hardware like digital filter chips and digital receiver chips.
Design of a Convolution Engine optimised for Reverb
A paper that covers issues surrounding implementation of convolution-based reverb processing for audio
DAFX - Digital Audio Effects
Clicking on the picture of the book gets you to...
A web site for a book on how to use DSP to create audio effects... has matlab m-files on the site
Spectrum Allocation Chart
This chart shows the allocation of the radio spectrum for its various uses.
DSP and A Hard Day's Night
A mathematician tries to use the DFT to unravel the chord that begins A Hard Day's Night.
Interesting, but his methods are flawed!
Tutorials on Using DSP for Audio Time Stretching and Pitch Shifting
Explains how to use DSP to make audio "run slower" without changing the pitch
or to change the pitch without changing the speed.
Links to Circuits for Guitar Effects
Web Site with LOTS of Links!!
There are lots of links here that you can explore!!!
How the mp3 algorithm works
A very rudimentary overview
Review of Speakers that Adapt to a Room's Frequency Response
Spec Sheet for the Speakers
Note the Frequency Response & Impulse Response plots!!!
Link to Fishman "Acoustic Imaging" Site (The video will start by itself after just a bit)
An interesting web site that talks about many of the frequency response ideas we
talk about ("time delay = phase shift", "time-domain view", "frequency domain",
"adjustment in frequency response... magnitude & phase") and it is all implemented
using DT methods in the frequency domain!!
