Electrochemical noise is electrochemical technique of growing interest. In the case of random signals obtained by discussed method the power spectral density is one of the fundamental characteristic of process. However its correct estimation imposes stationarity condition on signal under analysis. In the paper the authors present technique for quantitative assessment of degree of non-stationarity for electrochemical noise data by means of theWigner-Ville transform, which enables calculation of local power spectra.
