Digital signal distribution installation for e.g. premises of firm, has smoothing circuit with inductors mounted on branches, where inductors are seen as short circuits and high value impedances in low and high frequencies respectively

摘要

The installation has a smoothing circuit (45) interposed between main and auxiliary electrical energy distribution lines (4, 46). The circuit has inductors (47, 48) mounted on branches that connect strands of the line (4) to strands of the line (46) respectively. The inductors are seen as short circuits in low frequencies at 50 and 60 hertz and seen as high value impedances at high frequencies.
