Abstract (en)
[origin: WO2016184605A1] 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 (5-1), which is couplable to a positive sensor output of the sensor, and a negative signal input (6-1), which is couplable to a negative sensor output of the sensor, having a positive signal output (7-1) and having a negative signal output (8-1), having a first frequency-dependent resistance (C1H) between the positive signal input (5-1) and the positive signal output (7-1) and having a second frequency-dependent resistance (C1L) between the negative signal input (6-1) and the negative signal output (8-1), wherein the first and second frequency-dependent resistances (C1H, C1L) are designed to allow electrical signals at the prescribed signal frequency to pass in approximately unattenuated fashion, having a first voltage divider (11), which is arranged at least in part in parallel with the first frequency-dependent resistance (C1H) and is designed to divide a voltage between the positive signal input (5-1) and the positive signal output (7-1) using a prescribed ratio, having a second voltage divider (12), which is arranged at least in part in parallel with the second frequency-dependent resistance (C1L) and is designed to divide a voltage between the negative signal input (6-1) and the negative signal output (8-1) using a prescribed ratio. Further, the present invention discloses a control device for an electric machine.
