As I've said before, many text books are written by people who are more interested in showing the world how clever they are, rather than creating a tool for people to learn from.
It's so frustrating for us - we can see the "rabbit hole" that NM is in, but while he's determined to stick with these archaic texts, he's trapped. Despite everyone's efforts to help him see the light.
NM, you need to take a step back here. Learning how to learn is an important skill, and it appears that this is the problem here. A big part of that is learning how to decide what is worth concentrating on, and what can be put to one side. As a beginner, that's difficult. It can be difficult even if you're not a beginner (trust me). When I went to university, almost none of the staff there were willing to help me with that - I genuinely believe that was either because they didn't know how, or simply didn't want to. The thing is, I already knew more than some of them did. There's no quality more destructive in a teacher than insecurity or jealousy.
Here, you've got all these people trying to help you avoid all these problems. We have no ego or side. We just want you to help yourself. Please listen to us and give us some sort of indication that you've heard. Our patience is not limitless.
The Art of Electronics contains a good overview of FM modulation. Easy to read and understand, and easy on the maths. I have gone further in the past, and can categorically state that there's no need to unless you're doing specialist things. Fixing radios barely needs the basics, frankly. To put it another way, understanding the theory to a level beyond what Lawrence explained will not help you fix radios. In other words, it's a distraction. I'd go so far as to say "a waste of time". By all means come back to it later, but sort the basics first. Learn how an FM demodulator works.
