Hi Everyone,

Another month, another article. This one it titled "Coupling Signals 
and Noise into Circuits Using Magnetic Loops - A Troubleshooting 
Technique." The technique is applicable to both signal integrity 
issues as well as EMC troubleshooting.

-------------------------------------------------------
This month's Technical Tidbit discusses a method of injecting signals 
and noise precisely into circuits using magnetic loops for 
troubleshooting purposes.

Abstract: A square wire loop excited by a signal generator can be used 
to inject pulses or RF signals precisely into a circuit without 
disturbing circuit conditions. Used in this way, such a loop can be a 
significant aid in design troubleshooting. Suggestions for such uses 
are given.

The link to the article is the picture of two loops facing each other 
at the bottom of the home page at http://emcesd.com .
