A carrier wave is frequency-modulated using a sinusoidal signal of frequency and amplitude (a) Determine the values of the modulation index for which the carrier component of the FM wave is reduced to zero. For this calculation you may use the values of given in Appendix 3. (b) In a certain experiment conducted with and increasing (starting from zero volt), it is found that the carrier component of the FM wave is reduced to zero for the first time when What is the frequency sensitivity of the modulator
