Abstract
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. Performing jointly the computation of HDEV, ADEV, and TDEV give us additional useful possibilities of timing signal analysis.
