Electronic devices that cause high -frequency disorders, such as B. computer, can undesirably emit high -frequency energy via connected cables. The fault is led as a coat shaft, i.e. as a equal tier disorder from the device and radiated by the cable - the entire cable or Its shielding acts as an antenna. In order to dampen these disorders, the cables in the entire cross -section (possibly also several times) through a ferrite core. For the equal acid disorder, this arrangement acts through its inductance as a throttle with one or possibly several turns. However, the user signal, which is transmitted as a counter-tact signal, sees no inductance, since the magnetic fields of the streams that are back and forth on different veins compensate for each other. The mode of action corresponds to t.
