Abstract

A general theory is presented to estimate the uncertainty of a frequency comparison in the presence of dead time or time offset in the measurement. The uncertainties due to distributed dead time and lumped dead time with mixed power law noise type are calculated and compared. It is shown that using distributed measurements of frequencies can greatly reduce the uncertainty as compared to lumped measurements. When a time offset is present, two different methods are possible for the frequency estimation and uncertainty evaluation. we compare and discuss the different results for different methods.
