ABSTRACT:
For the offset compensation of a digital signal, particularly of a communication signal transmitted in a cordless digital communication system, a recursive digital filter is used. The recursive digital filter has at least one filter coefficient that is varied in a time-dependent manner. The recursive digitial filter has a first multiplying device multiplying symbols of the digital input signal by a first time-variable filter coefficient to obtain a digital output signal having symbols.
