The discrete Chebyshev algorithm for nonparametric estimation of autocorrelation function of electrochemical random time series

The discrete Chebyshev algorithm for nonparametric estimation of autocorrelation function of electrochemical random time series is presented. The algorithm is resistant to a trend of electrochemical noise. The discrete Chebyshev algorithm is tested using the model electrochemical noise corresponding to the equilibrium two-element Voigt circuit. The algorithm is used for nonparametric estimation of autocorrelation function of corrosion noise and electronic noise of measuring instrument.
