Hi All,

I have been keeping the keyboard busy over the last week. Just posted 
is the most recent article on my site http://emcesd.com concerning 
some of the effects that can occur when a signal path passes through 
multiple power/ground planes on a printed wiring board.

The experiment and data in the article relate to several other 
articles and papers on the site. Together, these papers and articles 
serve to emphasize that a signal always forms a loop, source to load 
and back again. What happens on the return trip can have a significant 
effect on board performance in many respects.

Doug
