Abstract
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.
