An apparatus for diagnosis of a communication channel, wherein a communication signal serves for data transmission and is a frequency-modulated signal. The apparatus includes a receiving circuit, which serves for receiving the frequency-modulated signal. The receiving circuit includes a monitoring unit, which serves for determining a signal parameter of the frequency-modulated signal. The receiving circuit also includes a demodulator, which serves to demodulate the frequency-modulated signal. The receiving circuit also includes a signal processing unit, which is connected with the demodulator and with the monitoring unit, wherein the signal processing unit, at least at times, serves for evaluating the signal parameter of the frequency-modulated signal determined by means the monitoring unit and, at least at times, for evaluating the demodulated signal.

Method and apparatus for diagnosis of a communication channel

An apparatus for transmission of electrical energy and data between a primary side and a secondary side. At least one transferring unit is provided between the primary side and the secondary side, that, on the secondary side, at least a first data channel is provided, which has at least one address, that, on the primary side, at least one frequency control unit is provided, which is embodied in such a manner that the frequency control unit sets the working frequency of the transferring unit corresponding to data to be transferred and/or corresponding to the addressing of at least the first data channel, that, on the secondary side, at least one load setting unit is provided, which is embodied in such a manner that the load setting unit sets the electrical load, which lies on the secondary side on the transferring unit, corresponding to data to be transferred and/or corresponding to the address at least of the first data channel.

Apparatus for transmission of electrical energy and information

An apparatus for transfer of electrical energy between a primary side and a secondary side. The apparatus includes: at least one voltage input on the primary side; at least one transformer, wherein the transformer has on the primary side at least a first winding area and a second winding area; and at least one voltage monitoring unit, wherein the voltage monitoring unit is embodied in such a manner, that it connects the voltage input with the first winding area or the second winding area as a function of a primary voltage present at the voltage input.
