Hey forum,
as a long-time reader, I want to use the opportunity to thank you all - Dave in particular, of course - for the valuable information you gather here. I really learned a lot from it

In the videos, Dave often mentions the importance of grounding circuits properly. However, that seems to be quite a controversial topic. Splitting a grounding plane between analog and digital parts, e.g., is discussed quite a lot. I assume the most precise answer would be found in field simulations. Let's just assume this is way out of scope and go back three steps.
I have not found an EEVblog video addressing questions such as
- What grounding scheme to use?
- What's a star ground, why is it beneficial, and how does it look like on a PCB?
- How to deal with mixed-signal circuits?
- What to do if there's resource constraints, say a single or double-layer board?
- How do I even know I'm having grounding issues if the circuit does not work?
If I'm too dumb to find it, I'll be happy to take a pointer (and of course also references to useful information from somewhere else). Otherwise, I think this might make an interesting video both from a theoretic and practical perspective.
Thanks for considerations and best regards
