Claim 4:
5. An electrical circuit for transmitting a useful analogue signal, which has a signal transmission path with an input path and an output path wherein a compensation circuit assigned jointly for a plurality of switches arranged in series is connected to the control connections of the switches and with which the useful analogue signal that is carried on the input path can be connected through to the output path or the signal transmission path can be interrupted, the plurality of switches in the switched-off state having a capacitance characteristic with a given curvature, wherein the electrical circuit further comprises a compensation circuit which substantially compensates a distortion of the useful analogue signal produced by the at least one switch of the plurality of switches in the switched-off state (OFF) and wherein the compensation circuit comprises at least one non-linear capacitance having a capacitance characteristic with a given curvature, which is connected via a capacitor to the control connection of each of the at least one switch of the plurality of switches, wherein the at least one non-linear capacitance is operated at a region of its capacitance characteristic at which its curvature is opposite to that of the capacitance characteristic of the at least one switch of the plurality of switches in the switched-off state, wherein, in the signal transmission path, two or more switches of the plurality of switches arranged in series are provided, which in each case have a control connection, wherein a compensation circuit assigned jointly for the plurality of switches arranged in series is connected to the control connections of the plurality of switches.
