Greetings,
While doing literature survey [1] and [2], I found that the authors have used the word "rms jitter" to report their jitter numbers. I am confused whether they mean cycle jitter (Jc) or edge-to-edge jitter (Jee)  since both of them are jitter and are rms quantities.
Could you please tell me which jitter are they refering to?

P.S. I know what each term mean.
