Optimization of the Procedures of Measuring the Parameters of Low-frequence Noise With 1/f Γ-type Spectrum 000_13.pdf

The short analysis of measurement methods for parameters of low-frequency (LF) noise with 1/fγ-type is considered. The authors show that the total measurement error of the LF-noise power spectral density (PSD) at the specified time of averaging is minimum at a certain (optimum) bandwidth of the filter. Measurement procedures for an exponent γ of PSD frequency dependence minimizing a total measurement error γ by results of measurement of PSD noise at two frequencies at series and parallel filtration are offered. The optimization essence at a series filtration comes down to optimum distribution of the specified total time of measurement at the specified relation of frequencies between measurements at the first and second frequency, and at a parallel filtration -to definition of the optimum relation of frequencies for PSD noise measurement at the specified total time of measurement. Methodical measurement error estimates for γare given at implementation of various measurement procedures depending on the γvalue.
