Real-time Assessment of Allan Deviation and Time Deviation

2007 IEEE International Frequency Control Symposium Joint with the 21st European Frequency and Time Forum, 2007
In this paper the methods enabling real-time Allan deviation (ADEV) and time deviation (TDEV) are presented. The idea of real-time quasi-parallel computation of ADEV and TDEV is described first. The results of experimental tests of the methods proposed for different conditions (numbers and lengths of observation intervals simultaneously analyzed) are ...

Joint real-time computation of Allan deviation, time deviation, and Hadamard deviation

EFTF-2010 24th European Frequency and Time Forum, 2010
The results of the experimental tests have proved the ability of the real-time computation of Hadamard deviation, Allan deviation, and time deviation performed jointly. The computation of the three parameters can be performed jointly simultaneously for numerous series and wide range of observation intervals as well as rather short sampling interval ...
