    摘要： A cable for the transmission of audio frequency currents with reduced distortion has at least one pair of electrical conductors insulated from one another. A ferromagnetic foil is closely (less than one half millimeter) applied to the conductors. The ferromagnetic foil couples the equal and opposite external magnetic fields generated by the signal currents. This greatly reduces distortion due to the frequency-dependent magnetic effects on signal transmission.

    摘要： A signal conductor is wound on a soft magnetic core with stepfunction permeability and extending for the length of the transmission line. A control conductor is also wound on the core and passes a parametric pumping signal, for example, at double the frequency of the information signal carrier frequency, to obtain continuous signal amplification along the transmission line and cable offsetting inherent line attenuation as it tends to affect the propagating information signal.
