Patent ID: 8107911

Claim:
A signal processing device comprising: a filter functioning as a signal processing element having settable filter coefficients for a predefined transfer characteristic; an application unit for amplifying or attenuating an output signal of the filter, the application unit configured to compensate partially for an effect of the predefined transfer characteristic of the filter based on a characteristic quantity of an input signal, the compensation being encumbered with a residual error; a detection unit for detecting a characteristic quantity representing the characteristic quantity of the input signal of an output signal of the signal processing element, the detection unit configured to output a detection value that represents the characteristic quantity of the output signal; a correction unit for applying a predefined correction value to the detection value for the at least partial compensation of the residual error, the predefined correction value being assigned to the predefined transfer characteristic; and a control unit for setting the predefined filter coefficients of the filter, the predefined amplification or attenuation of the application unit, and the predefined correction value of the correction unit, wherein the control unit is configured to select the predefined transfer characteristic from a plurality of transfer characteristics, wherein each transfer characteristic of the plurality of transfer characteristics is assigned a correction value.
