I enjoy all of Robert's videos which are huge value add to the community . I do hope that he will realise that most viewers are engineers who can follow the presenter , without continual interruptions to paraphrase and vectoring off at a tangent from time to time.
Hi Robert. Thanks for your very helpful videos. However, a suggestion for a video that I have not yet seen from you: An illustration - including hands-on formula/or the like - about how to calculate the impedance change in a microstrip trace when lined with stitching vias on both sides ... Useful variables would be via characteristics (hole size, internal pad diameter etc.), via center distance from microstrip trace edge, and via spacing along the trace. Hope you see this and find it relevant! Thanks, Jesper
Dear Robert: I hope you can introduce the actual use of the impedance calculator function in the ALTIUM DESIGNER software when you are free, such as how to use the ALTIUM DESIGNER software to calculate the impedance requirements for coplanar single-ended and single-ended 50R and coplanar differential and differential pair 90R. Thank you!
you know you could give your slides more screen real estate (especially center it better) if you closed the ribbon (simply by double clicking (on any tab) of the ribbon). the overview doesn't need closing as you place your self portraits over it.
Is the twisted pair "approach" even possible on a PCB, or is it just too unsymmetrical? It would at least reduce the cross talk problem to some extent.

Finally some good content, again we're here for advanced stuff, not for basic things.
Not all of us are here for complex things.
Спасибо, Роберт! Очень полезные у вас видео, на острие инженерной науки. Удачи в трудах!
I really liked the way the presenter (Saish) explained things. Wonderful job!

Thank you for your best channel ❤
Thanks for explaining the ads set-up

Why does the gap in the return plane on slide 13 result in a decrease of Z in the TDR plot? I thought it would increase Z.

Optical transmission would save so much headache.
