| 1. | Ferrite sheath current filters cannot effectively attenuate ground loop noise.
|
| 2. | Sheath currents can run along the outer sheath of a coaxial cable.
|
| 3. | Sheath currents can be caused by ground loops.
|
| 4. | Without the use of baluns, sheath currents will occur on the unbalanced line.
|
| 5. | Sheath currents may lower the efficiency of transmission and can interfere with nearby electronic devices.
|
| 6. | Ferrite sheath current filters are used for noise suppression, combating noise such as radio frequency interference.
|
| 7. | With such an arrangement, a ferrite bead would only be effective to reduce sheath current standing waves.
|
| 8. | Ferrite sheath current filters can only work effectively if a common-mode signal can flow on a line.
|
| 9. | With a balun, sheath currents can be avoided when a balanced line is connected to an unbalanced line.
|
| 10. | Transformer sheath current filters are used in low-frequency signal lines, where a ground loop otherwise can not be prevented.
