ABSTRAKT

It is shown in the paper that analysis of harmonic components of signal response generated by nonlinear objects subjected to a sinusoidal test-signal with the variable DC component can be considered as a process of selective filtering of variational attributes of macroscopic characteristics (e.g., current-voltage characteristic (CVC)) of such objects. Weighting functions and frequency characteristics for this process are obtained. It has been found that the frequency characteristics of the process must be consistent with the spectrum of informative variational attributes of macroscopic characteristics of objects.
