dear all
As we know, ISI is caused by cable's group delay distortion and amplitude attenuation. the groupdelay distortion represents the channel’s nonlinear phase distortion,which results in post-cursor signal distortions and adds jitters to the received data eyes.The received data eyes are no longer peaked at bit centres,and the eye diagrams are no longer symmetric. I have a question , for a given cable ,and we have its eye diagram. how can we kown how much jitter caused by cable's group delay distortion , and how much jitter caused by cable's amplitude attenuation. which way can we use to simulate through cable's s param, tran/ac or some others...
