I wanted to go back and watch Class-D
Audio Power Amplifiers: Operation, Efficiency and EMC but it is now gone. There are a few others that link to a page not found. have these been removed or just misplaced? There is a lot of good information in these video casts.
Not only are they rotten, but they are stinking and putrid, too!
I am trying to find out about this for you.
Your name sounds VERY familiar to me... Did you used to work at the IGBT company in Portland/OR/WA area? I forget the name... I was working at IR on their IGBTs at the time...
Audio Applications Engineering Manager
Dallas, TX USA
I believe they were up just a few weeks ago and it looks like EE Times did a recent update to their site.
Sorry to say I have never worked in the northwest...too depressing (rain/overcast)!
I am current responsible for audio products at a small company and I am expected to be the guru. Class D is rather new, and I am looking for information on layout tips (I can literally drown in all available information - I am hoping to find some real world resources like videos and/or presentations, etc.
The EMC video was great to show the test setup, but alas it is misplaced for the time being. :-(
Ok, I finally got this sorted out for you!!!!
The video may be found at: http://www.ti.com/ww/en/analog/elab/emc.html
Also, you may want to review Steve's presentation which is on this thread: http://e2e.ti.com/support/amplifiers/audio_amplifiers/f/6/p/52180/184516.aspx#184516
If you can log into the forum and mark this as Verified Answer, my boss will appreciate it! Otherwise, if you have any other related questions, HIT ME!
Whoops! Almost forgot about this. Thanks for retrieving the videos from the Nether Realm. It is always the good info that gets stuck somewhere in the void never to return.
Where might I find the appendices (equations) mentioned in the above referenced video ?

I did review that from the link you had posted before Don. It did not match the description of the mathematical framework advertised in the video as appendix one. If the stuff is gone I understand and I thank you for replying.
Matthew, I have attached the presentation that goes with the video. The video itself can be viewed over the video link provided earlier.
The presentation link provided earlier points to a different presentation, a later one on PCB layout for audio quality, EMC and thermal management. I hope it is useful to you.
