Abstract :
The aim of the paper is to extend the methodology of Blachuta, (1998, 1999) applied there to systems with ZOH and FOH to systems with FROH in order to determine the accuracy of the limiting formulas of both the intrinsic and discretization zeros at high sampling rates. The results can be applied to investigate the accuracy of certain approximate pulse transfer functions based on limiting zeros or their Pade approximation as it was done in Blachuta (1999)
