Abstract
Method to reduce the crosstalk of reception or crosstalk between pairs in a telephone cable with carrier frequencies provided that the couplings between the pairs are magnetic couplings with components c and g of opposite signs mainly increasing in absolute value with the frequency characterized because the coupling between two pairs ab and1 b1 a capacitor is balanced or compensated between a wire of the last pair (b1) and another wire of the first pair (a) and a capacitor of approximately the same value and a resistor in series between the same wire of the first pair (a) and the other wire of the last pair (a1) being disconnected the other wire of the first pair (b) logically allowing this arrangement permutations of b1 aa1 and b so that after 1 and 3 permutations a cable coupling is balanced with a real part and another imaginary one of opposite signs to the exists in the primitive case and after 2 permutations it is compensated in cable coupling with a real part and another imaginary part of the same signs as in the primitive case; an alternative arrangement consisting of also logically connecting in place of a capacitor between two wires a capacitor between these two wires and a capacitor between the two remaining wires possessing the two capacitors together the same capacitance as a capacitor and/or instead of a capacitor and of a resistor in series between the two wires a capacitor and a resistor in series between these two wires and a capacitor and a resistor in series between the two remaining wires having the two capacitors together the same capacitance as a capacitor and the two resistors together same conductance as one or the single resistor and also being the ratio of the capacitances equal to the ratio of the resistances.
