摘要： 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.

摘要： A signal under measurement x(t) is transformed into a complex analytic signal zc(t), and an instantaneous phase of the xc(t) is estimated using the zc(t). A linear phase is removed from the instantaneous phase to obtain a phase noise waveform Δφ(t) of the x(t), and the Δφ(t) is sampled at a timing close to a zero-crossing timing of the x(t) to obtain a timing jitter sequence. Then a difference sequence of the timing jitter sequence is calculated to obtain a period jitter sequence. The period jitter sequence is multiplied by a ratio T0/Tk,k+1 of the fundamental period T0 of the x(t) and the sampling time interval Tk,k+1 to make a correction of the period jitter sequence. A period jitter value of the x(t) is obtained from the corrected period jitter sequence.

摘要： A signal under measurement is transformed into a complex analytic signal using Hilbert transformation to estimate an instantaneous phase of the signal under measurement from the complex analytic signal. A zero-crossing timing sequence of the signal under measurement is estimated using the instantaneous phase. An instantaneous period sequence of the signal under measurement is estimated from the zero-crossing timing sequence to obtain a jitter of the signal under measurement from the instantaneous period sequence.
