TL;DR: In this article, the spectral density S y (f) of the function y(t) where the spectrum is considered to be one-sided on a per hertz basis is defined.

A Modified "Allan Variance" with Increased Oscillator Characterization Ability
David W. Allan,J.A. Barnes +1 more
TL;DR: In this article, the modified Allan Variance has been used to distinguish white phase noise (a = +2) and flicker phase noise, which is common for the short term instabilities of quartz crystal oscillators and active hydrogen masers.

Variances based on data with dead time between the measurements
J.A. Barnes,David W. Allan +1 more
TL;DR: In this paper, the effect of distributed dead time on the convergence of the two-sample variance has been investigated and a new bias function, B,(2,M,r,p,p) has been proposed to handle the commonly occurring cases.
