TheWigner-Ville distribution (WVD) method has been applied for the analysis of spontaneous oscillations of the anodic copper dissolution process. The nonstationary character of the investigated process has been shown. The observed current oscillations contain deterministic components not revealed in the classic Fourier spectrogram. The WVD spectrogram allows the identification of frequency bands of spontaneous oscillations. The observed deterministic components take the form of frequency bands, dependent on time. The main disadvantage of this type of analysis is the formation of the so-called cross-terms, which are oscillatory in character. However, it was shown that it is possible to reduce them significantly by a low-pass filtration.
