TLDR
In this paper, a tracking filter switching n switched paths, of band-pass type, is described, in which means (M, T) for taking a prefittre signal paths of the switching timing are constituted so that in said pre-filtered signal remains a part of the input signal.Abstract:
The invention relates to a tracking filter switching n switched paths, of band-pass type. This filter comprises means (M, T) for taking a prefittre signal paths of the switching timing. It is characterized in that the means (M, T) for withdrawing the prefiltered signal are constituted so tells that in said pre-filtered signal remains a part of the input signal (E) of the filter. Application to the filtering of a signal having a useful component of variable frequency associated with a high background noise.read more
