Abstract

There is described a device for removing an offset from a signal, the device comprising (a) a frequency estimation unit () for estimating a frequency of the signal, (b) an offset estimation unit () for estimating the offset in the signal by applying an adaptive low pass filter to the signal, wherein a cut-off frequency of the adaptive low pass filter is determined based on the frequency of the signal estimated by the frequency estimation unit (), and (c) a subtraction unit () adapted to subtract the offset estimated by the offset estimation unit () from the signal. There is also described a filter unit comprising the device. Furthermore, there is described a corresponding method of removing an offset from a signal as well as a computer program and a computer program product for performing the method by means of a computer.
