3) (40 pts) An FM modulated carrier is modulated by the following signal:
m(t) = 4 cos(2л * (1000) *t) volts
The modulator uses a frequency deviation of 3 KHz. The unmodulated carrier is:
*
c(t) = 5 cos(2π (100,000) *t) volts
a) (10pts) What would be a good estimate of the bandwidth of modulated signal?
