The message signal m (t) = 10 sinc(400t) frequency modulates the carrier c(t) = 100 cos 2πfct. The modulation index is 6.
1. Write an expression for the modulated signal u (t).
2. What is the maximum frequency deviation of the modulated signal?
3. What is the power content of the modulated signal?
4. Find the bandwidth of the modulated signal.
