EECE 301 Signals & Systems - Flipped              

What is Here?

 

 

Course Information

 

Lecture Notes and Video Lectures

 

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!

 

 

Some Review Material to Help You Get Up To Speed

Links of Interest

A. Learning Links

Textbook's Web Page 

    Has the following things:

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!!!

 

Speaker Impedance

 

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!!
