Models for the interpretation of frequency stability measurements
Abstract
The results of measurements of frequency stability are interpreted in the terms of models. Typically, these models are expressed as a power-law for the power spectral density. The experiments which provide the basis for these models are limited in their range and include neither zero nor infinite Fourier frequency. These problems are associated with the model and not the actual oscillators being modeled. By carefully taking into account actual limits of the device, and constraining discussions to be concerned only with quantities which can be observed in a practical sense, the problems of nonconvergence and nonstationarity are avoided. There is evidence that the typical Gaussian models may be inadequate.
