Abstract
A measuring apparatus is provided that includes: a timing jitter calculator for calculating the first timing jitter sequence of the first signal and the second timing jitter sequence of the second signal; and a jitter transfer function estimator for calculating a jitter transfer function between the first and second signals based on frequency components of the first and second timing jitter sequences. The jitter transfer function estimator calculates the jitter transfer function, for a plurality of frequency component pairs each of which is formed by a frequency component of a timing jitter in the first timing jitter sequence and a frequency component of a timing jitter in the second timing jitter sequence which correspond to approximately equal frequencies, based on frequency component ratios of the timing jitters in the first and second timing jitter sequences.
