Filter finished impulse response

It is about a numerical Filtre. The finished impulse response filter (RIF filter) is to be put in opposition with the filter to infinite impulse response (filter RII).

One speaks about finished answer when the way of calculating of the flood of exit depends only on the values of the flood of entry. So whatever the filter, its answer to an impulse will have an end value, stable, depend on the number of coefficients of the filter.

For an infinite answer filter, the preceding values of the flood of exit intervene as well as the values of entry in the calculation of the flood of exit.
