Abstract :
For pt. I see ibid., p. 1216-21 (1995). This paper concerns the asymptotic behaviour of parametric frequency-domain identification methods to model linear dynamic systems in the presence of nonlinear distortions, using random multisine excitations. Consistency is shown with respect to the general conditions. A function of dependency is defined to detect the presence of unmodelled dynamics, nonlinear distortions and to bound the bias error on the transfer function estimate
