A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.
Write equation for modulated signal What is average transmitted power & modulation index?
What is bandwidth using either Carson's rule or "universal curve"?
What is the bandwidth required so that the modulated signal contains atheist 90% of the power of the unmodulated carrier? Hint: Use Bessel functions to compute the sidelobe tone powers first.
