JITTER MEASURING DEVICE AND METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a jitter measuring device for sharply reducing a cost for measuring jitter by precisely finding jitter series from a data signal in a short time. SOLUTION: The jitter measuring device for measuring the jitter of a signal to be measured comprises a squarer for finding a squared signal 2N(N is a positive integer)-squaring the signal to be measured, and a timing jitter estimator for finding timing jitter series of the signal to be measured on the basis of the squaring signal.
