Degrees of Freedom for Allan Deviation Estimates of Multiple Clocks

摘要

The three-cornered-hat (TCH) technique is used frequently in the timing community to estimate the stability of single frequency standards (clocks) when the only measurement data available are paired differences. In previous work, we presented an analytic method to estimate the reduced degrees of freedom produced when using the TCH estimation technique. In this paper, we extend that method to estimate the reduced degrees of freedom related to the more general case of the -cornered-hat.
