can you explain slide 13 again.


quite similar to what Eric teaches.


Thank you Alfed and Martin.


sorry, my typo:  replace "non-resonant" with non-50 ohms"".



Thanks Al, I'am begining to understand.


Hello again,

So if I measure the null-to-null spacing in the S11 plot from a non-resonant transmission line and then calculate the delay using your formula from yesterday:  delta f in GHz) = 1/(2*Td) is Td also the group delay?


ukdave, thanks. That's often done on wafers as well, for failure analysis.

Good Afternoon, 9AM in the Morning here


Joe, here's the lonk to yesterday's slides


The Cal Structures are on the same board PANEL but not part of your finished board.


Joe I'll get the link for you.

Travel glitches kept me form the class yesterday. Is the slide show and audio archived?


No. I wouldn't go this year.


On EMI/SI/PI panel and will be in the Simbeor Booth



Anyone going to DesignCon next week?

Remember to post questions here

"I use airlines every week," said Al Neves, the self-proclaimed SI (signal integrity) Practitioner, at DesignCon 2013. He's also the Chief Technologist with Wild River ...

Note freq is in 10's of GHz


What would the group delay average be?

so boards usually cal structures on them? What if there is no real estate?

Would you please define group delay?


Remember to post questions here.

I'm going to need a refresher on Eigenvalues!

no audio, this webcast sucks!


Good evening from Valladolid, Spain in the West Europe
