Who wrote EMC guru"?  It wasn't me!!!!

  I just stated at the end that I had taken the referred Henry Ott courses
at HP's expense and the Howard Johnson's 4-day course at the expense of
StorageTek.  I don't consider myself a "guru", just been doing this for
some 35 years professionally and still do a bit of consulting.

I try my best not to blow my own horn.  If you believe it was me, I beg
forgiveness.

WIKI on ABBREVIATIONS I (and others) commonly use:

     CMC = Common Mode Choke
     DM = Differential Mode
     CM = Common Mode
     RF = Radio Frequency
     MHz = MegaHertz (or maybe for us fossils, Megacycles)
     Ω = Ohms (complex or pure resistance)
     Zo = Characteristic Impedance
     Zs = Source impedance
     Zl = Load impedance
     j = + or - and represents the complex portiin of an impedance....
minus is capacitive or bottom of the Smith Chart........positive is
inductive or top of the Smith Chart
     R = pure resistance (no reactance)
ask about others......
