1. A demagnetizing device comprising:
a circuit configured to be operatively coupled to an apparatus, the apparatus comprising a first signal circuit portion and at least one ferrite component, the apparatus being electrically connected to a coaxial cable that transmits data signals, the coaxial cable being electrically connected to a data network, wherein the first signal circuit portion is configured to receive a first parallel part of a transient signal and the data signals, and the first parallel part of the transient signal is operable to magnetize the at least one component, the magnetization being operable to cause a performance of the apparatus to drop from a designated performance level to a lower performance level with respect to receiving and transmitting the data signals, wherein the circuit comprises a second signal circuit portion and a demagnetizing coil, the second signal circuit portion configured to receive a second parallel part of the transient signal in parallel with the first signal circuit portion receiving the first parallel part of the transient signal, the demagnetizing coil configured to operate based on the second parallel part of the transient signal, the demagnetizing coil being operable to cause a continuous reduction in the magnetization of the at least one ferrite component so that the performance of the apparatus is maintained to be at least as good as the designated performance level with respect to receiving and transmitting the data signals. |
