Some traditional differential mode techniques
do not work in common mode situations
When differential mode solutions are applied to a common mode problem; many
of the techniques will prove ineffective. For example:
Reducing circuit loop area: The radiating signal is on the signal and
return path, so this will be ineffective. Using twisted pair wires or coax
will yield little in the way of signal reduction.
