Abstract

The various embodiments herein provide an improved system for communicating data over a wired connection. The system comprising a transmitting end, a switching circuit provided at the transmitting end to generate a propagating signal disturbance according to an input signal data received from a source network, a receiving end and a receiver circuit provided at the receiving end to detect the propagating signal disturbance and to regenerate the transmitted signal data from the received signal. The propagated signal disturbance is detected at the receiving end without a need for a common ground reference. The propagating disturbance is created by inducing an electron distribution change at one end of the wired connection and propagated along the length of the wire. The propagating disturbance is generated using one of an inductor, a capacitor and a switching device.
