Abstract

Digital filter for filtering a digital input signal with a variable filter length (l), it being possible to switch over the filter length (l) of the digital filter (8) as a function of a variable input clock frequency (fin) of the digital input signal without the ratio between the input clock frequency (fin) and an output clock frequency (fout) of the filtered digital output signal which is output by the digital filter (8) changing.
