Signal transfer assembly with capacitive coupling

A signal transfer assembly, comprising a signal source having a signal source output, a signal sink having a signal sink input and a signal sink input capacitance, and a communications channel, which connects the signal source output to the signal sink input in an electrically conductive manner, wherein the communications channel has a first signal terminal configured to connect the communications channel to the signal source output, a second signal terminal configured to connect the communications channel to the signal sink input, and at least one ohmic resistor connected in series between the first signal terminal and the second signal terminal, in order to transfer an electrical source signal-originating from the signal source-into an electrical sink signal entering the signal sink, wherein the at least one ohmic resistor of the communications channel with the signal sink input capacitance of the signal sink forms a low-pass filter with a filter cut-off frequency, wherein the low-pass filter subjects the electrical source signal to a low-pass filtering during transfer into the electrical sink signal, wherein, in the communications channel, a series connection of at least two capacitors is connected between the first signal terminal and the second signal terminal and in parallel to the at least one ohmic resistor, and wherein series connection of at least two capacitors raises the filter cut-off frequency of the low-pass filter in comparison with a communications channel without a series connection of at least two capacitors connected in parallel to the at least one ohmic resistor, and thus reduces the low-pass effect of the low-pass filter.
