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

首次在离散切比雪夫光谱学中考虑了电化学布朗运动。对以一阶正弦滤波器模式运行的模数转换器的输出信号进行计算机处理，可以测量布朗粒子坐标的电化学模拟物的离散切比雪夫光谱。结果表明，相对于归一化的切比雪夫多项式，存在切比雪夫功率谱密度。切比雪夫功率谱密度是针对输入短路的EVAL-AD7176-2SDZ评估板的腐蚀噪声的布朗坐标和本征噪声的布朗坐标确定的。首次，结果表明，电化学噪声布朗坐标的切比雪夫功率谱密度取决于一阶Sinc滤波器的输出数据速率。布朗坐标的Chebyshev功率谱密度的抗趋势方法可用于电化学装置和过程的噪声诊断。
