A transformer includes a transformer core, a first wire, which forms a first winding, and a second wire, which forms a second winding. The first and second windings are wound around the transformer core. A preformed insulation structure is arranged between the first and second winding and designed to space apart the second winding from the first winding and the transformer core. The preformed insulation structure further includes a first shell which at least partially encloses the transformer core with the first winding, and a second shell which at least partially encloses the transformer core with the first winding. The first and second shells are identical. One or more holes are defined in the first shell and the second shell. The one or more holes cover more than 10% of a surface of the preformed insulation structure.

The present invention relates to a method for transmitting a two-valued signal via a channel, a pulse train being output after the change of a signal level of the two-valued signal, and subsequently to the pulse train, a backswing is output. The present invention also relates to a circuit configuration for transmitting a two-valued signal having a magnetically coupled coil pair which includes an input coil and an output coil, at least two driver stages which are each connected to a terminal of the input coil, and an evaluation circuit which is connected to the terminals of the output coil, a capacitance being provided between a driver stage and a terminal of the input stage, and the input coil and the output coil each include two coil sections having windings in the opposite direction, the coil sections having the same winding direction of the input coil and the output coil being magnetically coupled.
