An FM signal uses a deviation of 100 kHz and a modulating frequency of 25 kHz.
(a) Calculate the modulation index.
(b) What is the bandwidth predicted by Carson's rule
(c) Use Bessel functions to find the bandwidth of the signal, ignoring all sidebands with an amplitude more than 40 dB below the amplitude of the unmodulated carrier.
(d) If the total power of this signal is 10 W, how much power is transmitted at the carrier frequency for the conditions described above
