This is probably too technical for most people here but if you are into DIY work this is by far the best video I have seen on basics of line filtering. It explains for example why there are multiple capacitors put in parallel. Why different devices like chokes are used, etc. And he does this in a very intuitive way. Nothing like the obscure college classes one takes. Likely even if someone is an engineer, this video would be a great watch for them.
It is a very long video but is reference material on the topic. English is Roger's second language but he does a better job on this than any native English speaker I have seen!
If you are at all an electronic hobbyist or into DIY audio, this is a must watch. As an aside, he is covering this in the context of a power supply for a tube amp!
There are more parts to this video which you can watch but I found this one episode to be all encompassing enough to watch by itself. Click on the Youtube symbol in the above player and then go to his channel for the rest.
