Help understanding how to solve this problem - Nyquist, Fourier?
(OP)
This is from an exam prep that provides the solution. I don't understand how they came up with 2*9. To me the solution should be 2*10 to reflect the +-5f0 = 10..
Ugh I am too far out of school to remember all this..Anyone?

I don't think it's much more complicated than that; provided you understand that square waves are made of the odd harmonics and you understand how AM sidebands work (nobody understands how FM sidebands work <- joke alert).
Beware that homework questions are explicitly not permitted. This one barely slips under the posting guidelines as it is an exam prep question.

Not sure why you are warning me because like you said, it is not a homework problem and I am not in school and don't do homework at this time.
Anyway, I don't work in commmunications I work in electrical power distribution and transmission so understandably this stuff is not fresh to me. I am reaching out to those individuals who have a good understanding of this while I search for understanding myself through books and online. Sometimes it helps to have a real person to aid in understading, like on a forum for example.
