      Hi, all.
      Have a good day everyone.

      I’m just simulating the RoF design to evaluate the eye diagram. But, the eye diagram was too bad. I suspect it because of the amplitude and bias value in the sine generator.
      Down here is the design that I attached. Anyone who can help me to trace the problem

      Good day,

      Your post doesn’t seem to include the attachment. Would it be possible to re-post with the attachment? Cheers.

      Hi, Marc Verreault…
      Since the file exceeded the maximum file size allowed, I’m just giving the snapshot of the eye diagram result.

      Good Nurul,

      The eye diagram actually looks very good! The Q factor is 21 (very high). I wouldn’t change a thing in your design. Cheers

      Hi Marc Verreault

      But I’m still confusing about the black rectangle in the up and down of the eye diagram.

      Hi Nurul,

      Yes, that does look strange at first view. If you reduce the number of samples do you still see the same? Cheers

      Hi, Marc…

      When I decrease the number no samples, the result shows an improvement. But, I’m still don’t know how to pick the exact value of no of samples. Can you help me?
