Abstract :
Zero locations of stochastic models have a significant influence on optimal prediction algorithms as well as on the convergence speed of identification methods. The possible zero locations for a sampled stochastic system are examined. In particular, it is shown and numerically illustrated that the sampled zeros can appear only in a restricted set within the unit circle. A complete analysis is given for second-order systems
