[Doug Smith <doug@xxxxxxxxxx>]

Hi Everyone,

For years the electronic fluorescent light over the table I do many of 
my experiments has been putting "fuzz" in some scope measurements. So, 
I decided to measure what was going on. This month's Technical Tidbit 
on my site is:

Abstract: Electronic fluorescent lights are capable of generating 
significant EMI. The nature of the EMI resulting from internal 
switching used by such a light is presented. The amplitudes measured 
are significant and could affect high impedance analog circuits.

The results are surprising in the amplitude observed at 48 kHz. Go to 
http://emcesd.com .  The picture of the scope probe and fluorescent 
light is the link to the article.
