Abstract
Abstract An arrangement for supplying current to a wideband transmission cable includes an all-pass circuit having a high-pass path (VPH) and a low-pass path (VPB) in which the signals in the transmission cable are recombined by virtue of the presence of a phase inverter. A current supply supplies current to the transmission cable via a supply point situated in the low-pass path.
