Abstract
An arrangement () and a method for digitally filtering a time-discrete digital signal, wherein the signal is transformed to the frequency domain using discrete Fourier transformation (), the signal is filtered in the frequency domain (), wherein a filter response can be adapted in real time as required to respond to changes in the interference environment, and the filtered signal is transformed back to the time domain using inverse discrete Fourier transformation () to create an output signal, and wherein bin frequencies of said signal in the frequency domain are translated by a real amount and the sampling rate of the output signal is changed by a real factor.
