Abstract
A filter apparatus () having a signal input () to which an input signal is applied which contains a useful component and a noise component, a fast signal path () and a slow signal path () arranged in parallel therewith. The fast signal path and the slow signal path are coupled to the signal input. The fast signal path contains a filter in order to prompt fast filtering of the input signal. The slow signal path contains a filter in order to prompt slow filtering of the input signal. An output of the slow signal path is coupled to the fast signal path by means of a signal line (). A signal output () which is coupled to the fast signal path has an output signal applied to it which essentially contains useful components of the input signal.
