Abstract: A device for signal processing includes a signal input, a control input, and a CIC filter of an nth order for filtering the input signal. The CIC filter includes n integrators, which are disposed one behind the other and include a memory in each case, and n is greater than one. For each of n−1 first integrators, the device includes an associated correction calculator for correcting an integration error using at least one signal value stored in the memory of the respective first integrator. The device transmits these stored signal values in response to the control signal to the associated correction calculators and to delete the memory of the remaining last integrator. Either the memories of the n−1 first integrators are also deleted, or the device includes a further correction calculator and the signal values are transmitted in response to the control signal also to the further correction calculator.

Abstract: A sensor system for determining at least one rotation characteristic of an element rotating around at least one rotation axis. The sensor system includes at least one sensor wheel, which is connectable to the rotating element, the sensor wheel having a sensor wheel profile. The sensor system also includes at least one position sensor and at least one phase sensor. The sensor system further includes at least one digital interface and at least one incremental interface, the sensor system being configured to output at least one absolute position signal generated with the aid of the position sensor via the digital interface and to output at least one incremental signal generated with the aid of the phase sensor via the incremental interface.
