Abstract
The method described in the first part for frequency-selectively measuring the transfer function and the noise power spectral density of the superimposed noise at the output of a disturbed, real system with nonlinearities using windowing was limited to time-invariant systems with stationary and zero-mean processes. Here, we investigate how this measurement method can be extended so that all correlations existing between the input and output signals can also be measured using windowing for a periodically time-varying system disturbed by a cyclostationary noise process. An extended version of the window construction algorithm presented in the first part is introduced, in which some degrees of freedom not used there can be used to appropriately influence the properties of the window sequence depending on the application. -- Das im ersten Teil beschriebene Verfahren die…
