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.
