A direct current magnetized hybrid transformed in a telephone line repeater has both its primary windings (l1, l2 and l1', l2' respectively) magnetically coupled to two pairs of secondary windings, one pair (l3, l4) creating the four-wire path in the repeater and the second pair is connected to the balance impedance (Zb). According to the invention the primary windings are each divided in two parts (l1, l1' and l2, l2' respectively) with, for exemple, the same number of turns (n1 and n2 respectively). The feeding voltage source (Eo, R1b, R2b) included in the repeater is connected between the connection point common for the winding parts. |
