Hello,
Regarding those Ferrite EMI Suppression "tubes" that are placed over signal wires to reduce noise, might someone please offer a bit on how used, and how effective they are ?
I have a small SDR radio Dongle that is connected to my PC via a USB cable.
There appears to be a fair amount of noise being picked up on the radio that is being radiated/induced from the PC, I believe.
e.g., should they be placed over both ends of the USB cable, at both the PC and at the radio Dongle ends ? Or, only at one end ? Why ?
I'll experiment, of course, but would like to hear your opinions on first.
Any thoughts on this would be most appreciated.
Thanks, Bob
