For a cable bundle between two devices but grounded at only one device, in general a ferrite sheath current filter is not effective.
12.
When used to eliminate standing waves, the ferrite sheath current filter must be placed at a current antinode, but not at standing wave nodes.
13.
High-frequency signal lines may attenuate or prevent sheath currents using a sheath current filter which is applied to a coaxial cable in or near the device.

"' Sheath current filters "'are electronic components that can prevent ground loops causing mains hum and high frequency common-mode signals can be prevented.
16.
Depending on the type, sheath current filters can remove or ameliorate hum in audio equipment, scanning frequencies in AV equipment and unwanted common-mode signals in coaxial cables.
17.
In addition, sheath currents caused by differences in ground potential at the ends of a coaxial cable to common mode signals that are superimposed on the useful signal as a noise voltage.
