The modified Allan variance (MVAR), also known as mod σy2(τ), is a variable bandwidth modified variant of Allan variance, a measurement of frequency stability in clocks, oscillators and amplifiers. Its main advantage relative to Allan variance is its ability to separate white phase noise from flicker phase noise. The modified Allan deviation (MDEV), also known as mod σy(τ), is the deviation variant of the modified Allan variance.
