Question

4.8 A carrier wave is frequency-modulated using a sinusoidal signal of frequency f m and amplitude A m (a) (b) Determine the values of the modulation index B for which the carrier component of the FM signal is reduced to zero. See the Appendix for calculating J 0 ( beta) In a certain experiment conducted with f m =1 kHz and in-. creasing A m (starting from 0 volts), it is found that the car-rier component of the FM signal is reduced to zero for the first time when A m =2 volts. What is the frequency sensitivity of the modulator? What is the value of A m for which the carrier component is reduced to zero for the second time?
