These records are automatically processed. The error information is subject to a
fast Fourier transform (FFT). FFT reveals the spectral components and their power.
Several window algorithms are provided to reduce the influence of leakage.
Jitter Distribution Over Time
Jitter has a more or less characteristic distribution over time.
The histogram of pure random jitter shows its Gaussian distribution, as illustrated
in the following figure:
Deterministic jitter periodically adds and subtracts a delay to/from the received
signal.
Jitter caused by a square wave or on/off signal has produced the following
histogram:
