Abstract
A method and a device for estimating the jitter of a first periodic signal with respect to a second periodic signal, comprising steps of: sampling the first signal by means of the second one; providing the result of the sampling to the input of a shift register triggered by the second signal; comparing at least the first two states and the last state of a current word formed from parallel outputs of the shift register with respect to a reference word; and counting the number of occurrences of the reference word within a given measurement period.
