ABSTRACT:
Disclosed is a transmission system for transmitting digital information via a power supply network. In one embodiment, there is a transmission device which comprises a generator for generating a simulated digital wave-form carrying the digital information to be transmitted, and a high-voltage injector to inject the generated simulated digital wave-form carrying the digital information into the power supply network. A receiving device is also disclosed, which comprises an analog detector for detecting predetermined harmonic frequencies of a signal frequency, and a logic device to output a logic signal corresponding to the output of the analog detector as said digital information.
