| 摘要 |
The invention relates to a personal computer (10), which is connected to a l ow- voltage power supply network (9) via a mains plug (11) and a mains socket (1 2) into which said plug is inserted, and which via said low-voltage power suppl y network exchanges messages with other apparatus by means of signals having a frequency of between 1 and 40 MHz. To suppress high-frequency interference signals which are generated by other apparatus connected to the low-voltage power supply network (9) via mains plugs (11') and other mains sockets (12') positioned near the above mains socket (12) or which are produced by signal reflexions at open line ends, an adapter (1) is interconnected which is inserted into the mains socket (12') and into which the mains plug (11') of the apparatus concerned is introduced. Although said adapter (1) connects every pin of the mains plug (11') with a jack of the mains socket (12'), reactors are situated in the phase conductor and the neutral conductor of th e adapter (1) which block signals in the frequency range of the transmission.< /SDOAB>
