Abstract
In various embodiments, a circuit arrangement includes a calibration filter set up to receive a signal based on a first signal and to provide a calibrated signal, the first signal being a signal which is provided by an analog/digital converter and is based on an analog signal, the analog signal being provided by at least one sensor of a sensor arrangement, a filter arrangement set up to receive a signal based on the first signal and to provide a second signal, and a controller set up to select a sensor-specific control signal dependent on the frequency response of the sensor from a plurality of control signals and to provide the calibration filter with said signal, the calibrated signal being based on the first signal and the sensor-specific control signal and corresponding or substantially corresponding to a predefined spectral mask in a predefined frequency range.
