- For clock jitter, there are three commonly used metrics: absolute jitter, period jitter, and cycle to cycle jitter.
- If jitter has a Gaussian distribution, it is usually quantified using the standard deviation of this distribution (aka. RMS). Often, jitter distribution is significantly non-Gaussian. This can occur if the jitter is caused by external sources such as power supply noise.
- ジッターがガウス分布を示す場合は、標準偏差として定量できる。
- ガウス分布でないジッタもよくある。電源などの外部ノイズ源からのジッタによくある。
