Abstract :
Estimates of the frequency stability of clocks and oscillators are given by statistics of frequency fluctuations. At long-term averaging times, TOTALDEV is a recommended statistic over ADEV, the Allan deviation. Simulation of common noise types with drift are used to compare TOTALDEV and ADEV. Comparisons show that the response of TOTALDEV is consistent at long term with drift taken out whereas the response of ADEV is not
