Abstract
An analytical expression for the modified Allan variance is given for each component of the model usually considered to describe the frequency or phase fluctuations in frequency standards. The relation between the Allan variance and the modified Allan variance is specified and compared with that of a previously published analysis. The uncertainty on the estimate of the modified Allan variance calculated from a finite set of measurement data is discussed.Keywords
