EECE 301 Signals & Systems - Flipped
For other info (e.g., syllabus, etc.) see go to the course page on Blackboard
I STRONGLY urge you to DOWNLOAD these videos and notes so you have your own local version...
That would avoid this: "Crap! The exam is tomorrow and I can't get to the on-line videos and notes!!"
Right Click the "DL MP4" link and choose "Save Link as..."
If you left click they will play if you have an appropriate player add-on for your browser
But... I've also provided a link to the videos on YouTube so you can watch them wherever you may be!

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.
Nice Frequency Response Java Applet
This java applet allows you to see Frequency Response Magnitude Plots for a variety of analog circuits
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!!!
Capacitors - Article on Different Types
Explains how they are made and how they behave
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!!
