This article describes a new method of the measure and analysis of the jitter phenomenon. Presented analysis is focused on the case of the telecommunication systems, but can be easily extended to other systems. This research is a continuation of the earlier work on the phase noise and jitter measurement systems. Method shown in this paper does not require generation of the reference clock in contrast to classic methods. It is rather based on the combination of the wavelet analysis and relational pattern recognition. This new approach to the jitter measurement problem gives very interesting results which are worth for further exploration. Authors give not only proposal but show measurement algorithm, which allows to estimate the jitter parameters by measure relation between the jitter wavelet base functions. In the background comparison of a classic and wavelet approaches to the jitter measurement problem is presented. In addition, such topics like the wavelet type, its order, as well as calibrating methods are also discussed.
