Hi All, I've been writing again, this time my monthly article is based on a technique originally described by Scott Roleson several years ago and updated with some new material.
This technique actually makes looking for things like heatsink resonances (that can cause EMC and maybe even SI issues) fun and relaxing! When is the last time you heard someone describe circuit or EMC troubleshooting as "fun?" Abstract: Structural resonances in equipment hardware can cause unwanted emissions from electronic equipment or make an existing emissions or immunity problem worse. A simple arrangement for measuring the resonant frequencies of physical structures in systems is described. The link to the article is the picture of the experimental test setup at the bottom of the home page at http://emcesd.com . There is also an audio discussion of this article on my podcast site: http://emcesd-podcast.com where the direct link to the article is: http://emcesd-podcast.com/2006/june/2006-0605.mp3 Can't download mp3 files? Download the following instead: http://emcesd-podcast.com/2006/june/2006-0605.dcs After download, change the extension from .dcs to .mp3 and the file will then be able to play on most computers. Since the last HFNews there have been two new podcasts posted. I am holding a fundraising seminar for the University of California at Santa Barbara on Friday, July 14th. ALL funds go to the benefit of the University. I am donating my time and equipment for this event. The seminar is my design troubleshooting course. The link to the course description is: http://emcesd.com/pdf/hffa_sem.pdf The University registration page for the seminar is: http://www.ece.ucsb.edu/Research/HFFA2006 Come learn some interesting, unique techniques and have a weekend of fun in Santa Barbara as well!
