On all-zero modelling of a recursive digital filter
Pei-Hwa Lo · 2005
In this paper, we investigate the feasibility and limitations of modelling a recursive digital system using an all-zero digital filter. It is shown that the accuracy of modelling depends on the pole of the recursive system and the number of collected data points. It is also shown that the long division method can determine the optimal performance for any given number of FIR digital filter stages.
