Claim 0:
1. An electrical circuit for transmitting a useful analogue signal, which has a signal transmission path with an input path and an output path wherein, in the signal transmission path, several two or more switches arranged in series are provided, which in each case have a control connection, 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 switches in the switched-off state having a capacitance characteristic with a given curvature, wherein the electrical circuit further comprises a compensation circuit assigned jointly for the series of switches which substantially compensates a distortion of the useful analogue signal produced by the series 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 connections of each of the series 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 series of switches in the switched-off state.
