In frequency modulation (FM), the message signal amplitude is A and its frequency is fm. If an experiment is conducted with fm = 2 kHz and a rapid rise in amplitude Am starting from 0V, it was noticed that the first time the carrier component in the spectrum was reduced to zero when the amplitude of the message signal Am = 4.5V. Find the frequency sensitivity of the modulator. (5 marks) (i) Find the value of Am for which the carrier component will be reduced to zero for the third time.
