(iii) What percentage of the average power is at 10.000MHz? (iv) What is the approximate bandwidth, using Carson’s Rule? 4. A certain sinusoid at a frequency f m Hz is used as the modulating signal in both an AM(DSB-C) and a FM system. When modulated, the peak frequency deviation of the FM system is set to three times the bandwidth of the AM system. The magnitudes of those sidebands spaced ± f m Hz from carrier in both systems are equal, and the total average powers are equal in both systems. (i) Determine the modulation index of the FM system and (ii) Determine the modulation index of the AM system....
