Popis:	This paper considers the problem of determining the true (nonsampling) variance of the Allan parameter-the main frequency instability characteristic of frequency generators, synthesizer, and standards in the time domain. The variables influencing the efficiency of estimating the parameter are determined and compared in magnitude. For frequency fluctuations with flicker noise power-law power spectral density, the parameter estimate accuracy is most significantly affected by the variance of the estimated average frequency—the quantity included in the Allan parameter and defining the quality of averaging over a finite time interval.
