Jim,

I'm  surprised you feel so strongly!

Throughout your RFI tutorial I see many references to the term "current 
balun". In a couple of places you put the term in parenthesis, or 
explain that it is really a common-mode choke; but in many other places 
the term is unqualified, and clearly is describing a common-mode choke. 
Chapter 6 is even headed "Baluns". In my view, anyone reading the paper 
could be forgiven for thinking that the correct term to use is "current 
balun".

Personally I have no problem with the term; if you choke (impede) 
common-mode currents, you are driving current balance.
