b) Frequency Modulation (FM) is a technique used to encode data on an alternating digital or analog signal. In the FM, the carrier amplitude remains constant, while the carrier frequency is changed by the modulating signal. A frequency carrier with a peak value of 70V is modulated by a fm = 11 kHz sine wave using Frequency Modulation (FM) techniques. It reaches a maximum frequency of 107.218 MHz and minimum frequency of 107.196 MHz. Determine; i) The carrier frequency and carrier swing. ii) The frequency deviation and modulation index. iii) Actual minimum bandwidth from the Bessel function table (Refer Appendix 1). iv) Approximate minimum bandwidth using Carson's rule. v) Their actual amplitudes and plot the frequency spectrum. vi) The total power transmitted if load resistance value is 50 2.
