hi people!

i just like to ask how the equation of FM signal is derived.

and how to expand it using the b.essel function?

thanks a lot!

 

Hi,

http://en.wikipedia.org/wiki/FM

has the derivation, I don't want to rekindle it from my huge communications book that I am trying to repress memories...

The bessel function gives the relative amplitudes of the harmonics across the spectrums.
