Abstract

An apparatus for carrying electrical data signals and electrical power over a power line is disclosed. The apparatus includes a data processing device, a power supply, and a data signal transceiver. The apparatus also includes an interference filter coupled to the power line and to the power supply and configured to reject electromagnetic interference. A coupling circuit that is electromagnetically coupled to the power line is also disclosed. The coupling circuit is configured to transmit and receive data signals carried through the power line. The coupling circuit is coupled to the data signal transceiver. The data signal transceiver is configured to transmit and receive the data signals to and from the data processing device.

Description

technical field [0001] Generally, the present invention relates to the technical field of power line networking, and further, the present invention relates to a signal interface between a computer power line and a computer data communication interface. Background technique [0002] Powerline technology (PLT) has been and continues to be rapidly introduced into the consumer market to support home networking and other local networking situations. For example, multiple computers in a home can be linked together by using the home's power lines to carry data communication signals at a frequency different from that used for power transmission. And other data processing equipment can be networked at home in a similar manner. For example, power line technology can be used to connect home application equipment and home communication equipment, such as telephones, video equipment, home security equipment, monitoring equipment, etc. [0003] Typically, personal computers (PCs) do not...
