ABSTRACT:
A method for correcting non-linearities of an output signal of an electrical component with the aid of a characteristics map that is defined by discrete interpolation points. In this context, the adjacent interpolation points of the characteristics map are ascertained as a function of at least one signal influencing the non-linearities of the output signal. Interpolation is carried out between these interpolation points, and a corresponding correction signal is ascertained as a function of the or each signal by an interpolation. The output signal of the electrical component is corrected as a function of the correction signal. To improve the correction of non-linear transfer characteristics and/or temperature responses of the electrical component, it is proposed that the or each signal for addressing the characteristics map be high-pass filtered, and the correction signal be ascertained as a function of the or each signal by the interpolation and a subsequent low-pass filtering.
