Hi All,

My Technical Tidbit article (http://www.dsmith.org) for this month deals
with signal corruption of digital and analog signals by magnetic fields
emanating from switching power supplies in a system. Because this is an
unlikely source of corruption, it is often overlooked at great expense.
The article covers an easy way to measure these fields to see if you
have a potential problem.

I would be interested in hearing other stories on unusual sources of
signal corruption from others on this list.

Doug
