摘要： An arrangement includes a transformer having a primary winding and a secondary winding, the transformer exhibiting an impedance across the primary winding, and an impedance synthesis circuit. The impedance synthesis circuit includes a transfer function element having a frequency spectrum. The transfer function element has associated a gain element and a current source controlled by the transfer function element. The impedance synthesis circuit is connected to said secondary winding, so that the transformer mirrors the impedance synthesized by the impedance synthesis circuit into the impedance across said primary winding. The primary winding is adapted to define the high voltage side of an XDSL splitter, while the impedance synthesis circuit connected to the secondary winding is inherently a low voltage circuit.
