A device for compensating resistive losses in a repeating coil that is part of a fork connection. The first winding (L1) of the coil is connected to the two-wire side of the fork while a second winding (L2) is connected to its four-wire side. The coil is also equipped with an additional winding (L3) whose speed is the same as the aforementioned second winding (L2) and which is connected in such a way that the voltage at its one end (p) is the same as the voltage drop caused by the resistance in the seconding winding (L2). This voltage is doubled in an amplifier (F3) to also match the resistive voltage drop across the first winding (L1) and is supplied to one input of a voltage-adding circuit (A), which receives the input signal of the four-wire side at its other input. This output thereby supplies a signal that compensates for the losses in the first and second windings (L1, L2) to the other end of the additional winding (L3).<IMAGE> |
