Go ahead. Type my question into Acrobat:
What is the best, generic solution for a wall wart or other switcher
that is spewing trash from 500 kHz to 30000 kHz?
OBVIOUSLY, that doesn't bring anything up.
I have all those books and I have read about half of the PDF cited,
but none of that answers my question.
When someone asks "I've got one of those stupid switching supplies and
it puts hash everywhere - what do I do?" (and for whatever reason,
they can't replace it with a transformer), what is the answer?
