This paper describes a new method for extracting both instantaneous and rms sinusoidal jitter from phase-locked loops (PLL) output signals. The method is based on analytic signal theory and utilizes the Hilbert transform to extract phase information from a PLL signal. Both the theoretical basis and fundamental concepts of the new method are explained. A unified review of conventional methods is also presented. Results of Matlab simulations validate the performance of the new method for measuring jitter, and it is further validated by comparing experimental sinusoidal jitter results with those of a time interval analyzer.
