The invention relates to a filter device (100) having a signal input (101) to which an input signal containing a useful component and a noise component, a fast signal path (102) and a slow signal path (103) arranged parallel thereto, wherein the fast signal path and the slow signal path are coupled to the signal input, the fast signal path includes a filter for effecting fast filtering of the input signal, the slow signal path includes a filter to effect slow filtering of the input signal, and an output of the slow signal path over one Signal line (106) is coupled to the fast signal path. At a signal output (104), which is coupled to the fast signal path, there is an output signal which essentially contains useful components of the input signal. |
