抖动jitter的分类

Depending on how the jitter timing is defined, jitter is classified into phase jitter, period jitter, and intercyclic jitter. Phase jitter is an accumulation of the difference between the ideal clock of the clock edge and the measured signal, and it is called long-term jitter or accumulated jitter depending in the case. Period jitter expresses the variation in a clock period and intercyclic jitter the variation in the difference between the periods of adjoining clocks.
根据抖动定时的定义方式，抖动分为相位抖动、周期抖动和循环间抖动。相位抖动是时钟边沿的理想时钟与被测信号之间的差值的累积，根据情况称为长期抖动或累积抖动。周期抖动表示相邻时钟周期之间的时钟周期和周期间抖动的变化。
