Data transmission system for electrical, optical, or magnetic energy sources, has impedance adjustment unit for adjusting an input impedance of energy receiver according to value of first data signal

摘要

A data transmission system has an energy source (10), with an output (12), and energy sink (receiver)(20) with an input (22) for receiving energy, and a transmission path (30). An impedance adjustment unit (40) adjusts an input impedance of the energy sink (receiver) (20) according to the value of the first data signal (DS1). A measuring and evaluation unit (50) detects the power outputted at the output (12) of the energy source (transmitter) (10) so as to make available, depending on the instantaneous value or time characteristic of this outputted power, a first reception signal (ES1) dependent on the first data signal (DS1). An independent claim is included for a method of transmission of a data signal.
