This article describes a technique for operating a personal computer (PC) network at lower than usual power levels, while avoiding intermodulation distortion characteristically expected for such operation. The latter result is achieved by insertion of filters in reception and transmission paths between each network node adapter and the network cable, to reduce distortion elements from signals transmitted on the cable and remove distortion elements from received signals. When two differing power levels are presented to amplifiers of a PC network, intermodulation and distortion result at other frequencies and possibly at the frequencies where communication is going on.
