The real trick to understanding this will be to develop an understanding
of the IQ representation of RF signals. Seeing what an FM signal looks
like on an IQ diagram, and seeing what an AM signal looks like, and
understanding why those signals look the way they do, is really the key
to understanding the fact that every arbitrary signal can be broken down
into FM and AM components.
Can you (or anyone) recommend a book or article that would show and
explain it?
I'm curious and would be happy to finally understand the quadrature
modulation in practice (and why, for example, we extract the USB from I/Q
signal by multiplying I by 1 and Q by -j, I never really understood that).
