I'm beginning my foray into electronics with no formal education, so I'm a complete hacker.
I'm designing circuits with microcontrollers, stepper motors and lighting and I'm thinking ahead a bit and trying to account for possible EMI.
I've read about the two forms of EMI radiated and conducted but I'm not sure about anything past this. Websites I've seen generally describe what it is and general classes of sources of the stuff, but I'm not sure how to move on from the basics. I don't have an oscillascope, but even if I did, I wouldn't know what to point at what.
1. The question that I currently am trying to solve is power over ethernet... and the obvious EMI potential from running data along side power.
I found this: https://e2e.ti.com/support/power_management/power_interface/f/204/p/193984/693040
The first response post has two links but I couldn't find anything useful in them - bit too advanced.
2. ICs - I'm reading that even they can be sources of EMI and given how thin some traces can be, how do you make sure your design won't get affected?
3. DC lighting circuits, are these potential sources for EMI?
4. How do you detect EMI? Say I have a stepper motor, how do I go about detecting how far away you need to be away from it and its cabeling?
5 Is there some best practice for designing for EMI?
Hopefully someone can point me in the right direction.
