5 - Algorithme de filtrage rapide pour les filtres à phase linéaire
Prado · Traitement du signal · 1993
A simple method for the implementation of a fast algorithm of linear phase FIR digital filtering is proposed here . The algorithm allows to use both the symmetry of the impulse response and the disponibility, on most of the new DSPs, of the one cycle instruction multiplication, addition and delay (z 1 ) . A comparative study on a personnal computer shows that the gain of computation time is about 20%.
