Since most PCBs include digital and analog signals.
I want to get some ideas how to define each section for analog and digital parts.
How to layout communication traces between analog chips.
Since the star ground is the best, in most of systems there is one main star and few sub stars, how I should connect signal sub star with main star?
Since every sub star can generate noise which can be coupled to digital signal, how can I avoid this?
Using differential signals? and how to avoid ground loop?
Thanks.
