Abstract :
A drift-rate estimator constructed from four values of the cumulative sum of clock residuals is shown to have good error performance in the presence of the five standard power-law noises. A comparison table of several drift estimators is given. The bias and variance (or equivalent degrees of freedom) of a modified Allan variance estimator incorporating drift, removal is calculated
