Abstract
A parametrized s-to-z-plane map is introduced, where the conventional bilinear map and backward and forward Euler rules appear as special ca ses. Time and frequency-domain characteristics of the map are discusse d, along with a simple technique for applying this map to adaptively r educe truncation error in the continuous-time to discrete-time convers ion problem, An example illustrates the method and its potential for y ielding more accurate discrete-time models over conventional approache s.
