Abstract: A checking device for a data preparation unit, including a preparation element for preparing sensor data for a data transmission; and a comparator for comparing the sensor data with the prepared sensor data; a fault of the data preparation unit being detected in the event that the prepared sensor data do not match the sensor data.

Abstract: A method is provided for suppressing interferences in a sampling process. The method includes the method step of sampling an analog useful signal at a sampling frequency f as well as determining whether an interference amplitude is present. In the presence of an interference amplitude, a stochastic shift of the chronologically equidistant sampling points in time, which are determined by the sampling frequency f, is carried out within a range [??t; +?t] (21) around the equidistant sampling points in time, ?t being the maximum shift. Subsequently, a resampling of the analog useful signal is carried out. It is redetermined whether an interference amplitude is present. In the case of the continuous presence of an interference amplitude, a change in the absolute value of the maximum shift |?t| is carried out and the process is restarted with the method step of stochastically shifting the sampling points in time.

Abstract: A method for interference suppression of a sampling process includes sampling an analog signal with a sampling frequency f, and determining whether an interference amplitude is present. The method provides that if an interference amplitude is present, the sampling frequency f is increased or decreased, and the method begins again with the sampling of the analog signal with the increased or decreased sampling frequency. In addition, a device is described for carrying out the method.
