Abstract (en)

[origin: DE19940926A1] The invention relates to a filter unit, comprising a decimator (2), core filter (1) and an interpolator (3). According to the invention, the sampling rate is decreased by a fractional sampling rate modification factor L/M, prior to the core filtration process. This allows the construction of a simple filter structure which can be universally used. Parallelisation achieves a structure whose clock rate can be freely modified.
