I *think* it may be more than "not enough samples", and imply that "up" is relative rather than absolute, so you need to do some sample-window analysis. But I am only speculating, and it would be good to have an answer from someone who actually knows.
@yjweaver5108 Good question. By "nothing" I mean the eye is closed. I explain the situation more clearly in this TH-cam timestamp: th-cam.com/video/YoOwy7y0Lto/w-d-xo.htmlsi=DDXqv1JolKbmYEbh&t=304
Great video, I probably would have never heard of Donald if I hadn't seen this podcast. It really got me thinking about the complicated technology enabling some of the newest generations and I discovered that 224G exists.. wow.
Equalization is essentially an amplification and filtering scheme as a function of frequency, and which may be nonlinear, which allows a signal to be recovered from a noisy bitstream. It is part of the interface standard and the circuit that performs the function is built into an integrated circuit (at the Rx end or Tx of a link).
@@Zachariah-Peterson Thank you; this might be worth a video too. Well, it definitely would be, but I'm not sure whether or not the right way to do it meshes well with your regular style/format.
At 14:40 he mentions a scope probe on a signal will see nothing. What does he mean by this ? Is it because the scope isn’t high enough bandwidth?

Online in some way would be better than nothing for those of us who cannot attend in person.
And what is “equalization “ ?

My book, articles, and LinkedIn posts are a great way to start learning about equalization. See the show notes for details.
