and what is the value of the carier that must be used

[tex]s(t) A \sin(\omega t)[/tex]

Here [tex]\sin(\omega t)[/tex] is the carrier signal, [tex]\omega[/tex] is its angular frequency, [tex]A[/tex] is a constant, and [tex]t[/tex] is time.

FM modulation is the following:

[tex]A \sin(B s(t) t)[/tex]

[tex]B[/tex] is a constant, and the other variables are the same as they were above.

I don't know the specifics of how these are used in radio.
