Аннотация:For the first time, the electrochemical Brownian motion is considered in the context of discreteChebyshev spectroscopy. The computer processing of output signal of analog-to-digital converter operatingin the first-order sinc filter mode enables measuring the discrete Chebyshev spectrum of electrochemicalanalog of Brownian particle coordinate. It is shown that there is the Chebyshev powerspectral density with respect to the normalized Chebyshev polynomial degree. The Chebyshev powerspectral density is determined for the Brownian coordinate of corrosion noise and for the Brownian coordinateof intrinsic noise of EVAL-AD7176-2SDZ evaluation board with a shorted input. For the first time, itis shown that the Chebyshev power spectral density for the Brownian coordinate of electrochemical noisedepends on the first-order sinc filter output data rate. The trend-resistant method of Chebyshev powerspectral density of Brownian coordinate can be used for the noise diagnostics of electrochemical devicesand processes.
