Abstract
The features of measurements of the parameters of low-frequency noise with a spectrum of the form 1/fγ of electronic components are considered. Expressions for the systematic error in determining the exponent γ from the results of single measurements of the spectral power density of the noise by a direct estimate at two frequencies, taking thermal and shot noise of the monitored article into account, are obtained and analyzed. Recommendations on minimizing the total error in determining γ are given.
