Abstract
A method of transmitting a communication signal and electric power between two user stations of a bus system includes coupling the communication signal into a bus line via a low-pass filter that filters the communication signal, such that signal frequencies below a cut-off frequency of the low-pass filter are coupled into the bus line of the bus system. The method also includes coupling, using a power coupling device, electric power in the form of a high-frequency signal into the bus line, transmitting the communication signal and the electric power as a bus signal to an electrical load using the bus line, and decoupling the communication signal from the bus line via a low-pass filter that filters the bus signal, such that signal frequencies below the cut-off frequency of the low-pass filter are decoupled from the bus line of the bus system.
