摘要： Timing jitter sequences Δφj[n] and Δφk[n] of respective clock signals under measurement xj(t) and xk(t) are estimated, and a timing difference sequence between those timing jitter sequences is calculated. In addition, initial phase angles φ0j and φ0k of linear instantaneous phases of the xj(t) and xk(t) are estimated, respectively. A sum of a difference between those initial angles and the timing difference sequence is calculated to obtain a clock skew sequence between the xj(t) and xk(t).

摘要： A signal under measurement is transformed into a complex analytic signal using a Hilbert transformer and an instantaneous phase of this analytic signal is estimated. A linear phase is subtracted from the instantaneous phase to obtain a phase noise waveform. The phase noise waveform is sampled in the proximity of a zero crossing point of a real part of the analytic signal. A differential waveform of the sample phase noise waveform is calculated to obtain a differential phase noise waveform. An RMS jitter is obtained from the phase noise waveform, and a peak-to-peak jitter is obtained from the phase noise waveform.

摘要： A clock signal xc(t) that has been converted into a digital signal is transformed into a complex analytic signal zc(t), and an instantaneous phase &THgr; of the zc(t) is estimated. A linear phase is removed from the &THgr; to obtain a phase noise waveform &Dgr;&phgr;(t). The &Dgr;&phgr;(t) is sampled at a timing close to a zero crossing timing of the xc(t) to extract the &Dgr;&phgr;(t) sample. A root-mean-square value &sgr;t of the &Dgr;&phgr;(t) samples is obtained, and a differential waveform of the extracted &Dgr;&phgr;(t) samples is also obtained to obtain a period jitter Jp. Then a root-mean-square value &sgr;p of the Jp is obtained to calculate a correlation coefficient &rgr;tt=1−(&sgr;p2/(2&sgr;t2)). If necessary, an SNRt=&rgr;tt2/(1−&rgr;tt2) is obtained. The &rgr;tt and/or the SNRt is defined as a quality measure of a clock signal.
