Very good. You must have done some Googling to find all those terms.

They do make filters for smoothing out the ripple that comes from converting
AC to DC. Ever tried one of those? Most of them are low pass. Raise the
frequency and the filtering is more effective.

I never said that arcing brushes would pass EMI/RFI standards. The subject
was on the power wiring. A low pass filter would block the higher frequencies
on that path. What you do on the antenna connection is anothr matter.
