Abstract

This paper describes the new method of time-interval-error (TIE) estimation and prediction. This method is very useful for standard clocks characterization and can be applied in high precision measurement and telecommunication systems with high resolution of the time-base. TIE can be easily and fast calculated using only two parameters obtained during calibration process. Moreover, it is very simple method for clocks comparison and can be applied in time-interval measuring systems (TIMS) for calibration or TIE calculation. This method allows to calculate an accumulated jitter and TIE as a function of the clock cycles. The measurement system, specially accommodated for jitter measurements and their application for estimations or predictions of jitter parameters will be also presented and discussed.
