Abstract
Mottagerkretsen som tjener til oppbygging av overføring overføringssystemer med kobberkabler som kan oppvise forskjellige kabelegenskaper, spesielt lengde og diameter, omfatter en mottakerenhet (RX) for digital signalbehandling, som kan forbindes med en scndcenhet (TX) over et filter (FR) og en kobberkabel (SL1, SL2), hvor filteret (FR) for kompensasjon av dempningsforvrengninger er utformet med en slik høypasskarakteristikk at signalandeler i området ved lavere frekvenser i det minste dempes så mye at dynamikken til signalene som overføres over kobberkabelen (SLl, SL2) med det størst mulige ledningsdiameter, reduseres så mye at oppløsningen til digitaldelen til mottakerenheten (RX) er tilstrekkelig til deres behandling og at signalandelene i området for lavere frekvenser maksimalt dempes så mye, at den maksimale opptredende dempning ved kobberkabler (SL1, SL2) med minst mulig ledningsdiameter og uten bruk av filteret (FR) i det benyttede frekvensområdet, i praksis ikke økes ved bruk av filteret (FR).The receiver circuit which serves to build transmission transmission systems with copper cables that can exhibit various cable characteristics, especially length and diameter, comprises a digital signal processing receiver unit (RX) which can be connected to a screen unit (TX) over a filter (FR) and a copper cable ( SL1, SL2), wherein the attenuation distortion compensation filter (FR) is designed with such a high-pass characteristic that at least lower signal frequencies at least attenuate the dynamics of the signals transmitted over the copper cable (SL1, SL2) with the greatest possible wire diameter, is reduced so much that the resolution of the digital part of the receiver unit (RX) is sufficient for their processing and that the signal proportions in the lower frequency range are attenuated to the maximum, so that the maximum occurring attenuation of copper cables (SL1, SL2) with the least possible wire diameter and without use of the filter (FR) in the frequency range used, in practice does not increase es using the filter (FR).
