     This class allows designing, loading, and applying a digital filter to a signal. The filter
     coefficients can be provided directly, or computed from a specific frequency response function
     (FRF). In this latter case, the filter is designed as a minimum-phase FIR filter, and the

         Whether they are derived from the provided FRF or specified directly, the filter
         coefficients are linked to the sampling frequency value that is given in the argument
         ``sampling_frequency`` of the ``Filter`` class. As a consequence, the signal to filter
-        ``signal`` must have the same sampling frequency. If necessary, use the :class:`.Resample`
