An FM signal has a deviation of 10 kHz and is modulated by a sine wave with a frequency of 5 kHz. The carrier frequency is 150 MHz, and the signal has a total power of 12.5 W, operating into an impedance of 50 .
(a) What is the modulation index
(b) How much power is present at the carrier frequency
(c) What is the voltage level of the second sideband below the carrier frequency
(d) What is the bandwidth of the signal, ignoring all components that have less than 1% of the total signal voltage
