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. Doug -- ___ _ Doug Smith \ / ) P.O.
