About 2004 I found an interesting serie of EMC articles by Keith Armstrong (for many years I didn’t know if Keith is a woman or men name). Later they became no accessible, but when I tried to find them few years ago I found them once more:
I wonder why previously my links were changed to rectangles (in source they were just lines) and now it looks my links are lines in source and in result. In both cases these are links to pdf-s.
And probably the same but modified:
Change 1 in ‘part_1’ in address to 2,3,4,5,6 to get the rest.
I found those time many, many pdfs googling for EMC, but these in my opinion are the best compendium of all EMC subjects.
