Abstract
The present invention discloses a signal processing device for processing a differential signal from a sensor at a prescribed signal frequency, having a positive signal input (-), which is couplable to a positive sensor output of the sensor, and a negative signal input (-), which is couplable to a negative sensor output of the sensor, having a positive signal output (-) and having a negative signal output (-), having a first frequency-dependent resistance (CH) between the positive signal input (-) and the positive signal output (-) and having a second frequency-dependent resistance (CL) between the negative signal input (-) and the negative signal output (-), wherein the first and second frequency-dependent resistances (CH, CL) are designed to allow electrical signals at the prescribed signal frequency to pass in approximately unattenuated fashion, having a first voltage divider (), which is arranged at least in part in parallel with the first frequency-dependent resistance (CH) and is designed to divide a voltage between the positive signal input (-) and the positive signal output (-) using a prescribed ratio, having a second voltage divider (), which is arranged at least in part in parallel with the second frequency-dependent resistance (CL) and is designed to divide a voltage between the negative signal input (-) and the negative signal output (-) using a prescribed ratio. Further, the present invention discloses a control device for an electric machine.
