Abstract
A telecommunication system for transmission along power supply lines of modulated information signals having a selected carrier frequency. The system includes a plurality of communication devices connected along the supply lines, each including a microcontroller and a modem. The modem includes an interface module which establishes a link to the power supply lines for modulated information signals, a transmission module which contains a digital modulator followed a digital/analog converter, and a receiving module. The receiving module includes a digital filter connected between an analog/digital converter and a digital demodulator. The digital filter is adapted to the carrier frequency of modulated information signals present on the power supply lines, whereby the modem can operate at any selected frequency over a broad frequency range.
