Abstract

A filtering device (100, 300) includes a low-pass filter (101, 301), a noise estimation circuit (102, 302) and a first combining circuit (103, 303). The low-pass filter (101, 301) receives and filters a pre-filtering signal (S pre , I pre ) to generate an output signal (S out , I out ) of the filtering device (100, 300). The noise estimation circuit (102, 302) estimates an estimated noise signal (S noise , I noise ) according to the output signal (S out , I out ) and the pre-filtering signal (S pre , I pre ). The first combining circuit (103, 303) subtracts the estimated noise signal (S noiser I noise ) from an input signal (S in , I in ) of the filtering device (100, 300) to generate the pre-filtering signal (S pre , I pre ).
