Please explain whole part a and b with steps, thank you very much.

Q1.(a) A 100-MHz carrier is frequency modulated by a 10-kHz sinusoid so that the pealk frequency deviation is 100 Hz. Determine (i) he approximate bandwidth of the FM signal:(5 marks) Ans (ii) the bandwidth if the modulating signal amplitude were doubled; (5 marks) Ans: (iii) the bandwidth if the modulating signal frequency were doubled; (5 marks) 0 Ans 4ok (iv) he bandwidth if both the amplitude and the frequency of the modulating signal were doubled. (5 marks) ms 4okHs Ans: kHz. (b) Using Carson's rule, repeat the above problem with a peak frequency deviation of 30 (i) the approximate bandwidth of the FM signal; (5 marks) Ans: (ii) the bandwidth if the modulating signal amplitude were doubled; (5 marks) Ans: 4okH (iii) the bandwidth if the modulating signal frequency were doubled(5 marks); the bandwidth if both the amplitude and the frequency of the modulating signal were doubled. (5 marks) (v) oKH
