(b) THREE (3) FM signals are multiplexed together and share the frequency spectrum of 88 MHz to 92 MHz. The technical specifications for each signal are as follows: • Modulating signal frequency: 90 kHz • Peak frequency deviation: 270 kHz • Guard band of 100 kHz (i) Calculate the bandwidth required for each of the FM signal. [3 marks] (ii) Propose the carrier frequencies and frequency planning for the FDM system. 16 marks) (iii) ONE (1) additional FM signal is to be multiplexed into the existing frequency spectrum. Suggest a strategy on how to accommodate the request. Justify your strategy using calculations. [4 marks
