A decoupling network for blocking high frequency communication signals on power lines. The network includes a filter having a first series element (10) for connection to a power line, a second series element (11) for connection to the same or another power line, and a shunt element (12) connected between the series elements and across two power lines. The shunt element acts as a short circuit to high frequency signals, thereby blocking passages of communication signals through the network. In one embodiment, a signal processing circuit (13) is inductively coupled to the series elements for processing communication signals from the supply authority and from consumers. The network prevents the communication signals from passing directly from the supply authority to the consumers, or vice versa. |
