The methods enabling real-time calculation of two commonly used parameters of timing signals – Allan deviation (ADEV) and time deviation (TDEV) – are presented in this paper. The idea of real-time computation of both parameters is described. The results of experimental tests of the methods enabling separate as well as joint real-time ADEV and TDEV computation are presented and discussed.
