Abstract
The invention relates to a device (300) for controlling a sensor (310), comprising a converter unit (320) for converting an input signal (365) into a control signal (360) for controlling said sensor (310), and a comparison unit (330) for determining a differential signal (370) that indicates the difference between said input signal (365) and control signal (360). The device also comprises a feedback unit (340) for regulating the input signal (365) using said differential signal (370). A differential signal (370) transfer function has a zero point at a sensor (310) operating frequency which does not equal zero.
Claims14
A device for controlling a sensor, comprising
- a converter unit for converting an input signal into a control signal for controlling the sensor;
- a comparison unit for determining a difference signal that indicates the difference between the input signal and the control signal;
- and
- a control unit for controlling the input signal by means of the difference signal, wherein
- the control unit generates a transfer function of the difference signal by processing the difference signal and by feeding back the processed difference signal to the input signal;
- the transfer function of the difference signal has a zero point at an operating frequency of the sensor;
- and
- the operating frequency is different from zero.
