1. What is the advantage of angle modulation for (noise and interference), the bandwidth of transmission and the average power of the transmission? comparison with the amplitude modulation 2. Explain briefly when the frequency modulation can be NBFM and WBFM? Explain effected NBFM and WBFM on the bandwidth for transmitted signal? 3. In the FM transmitted signal used to modulated message signal with 3 KHz and the frequency deviation is changed to get on the amplitude of the first sideband equal maximum amplitude, used the figure (4), calculate B and calculate the bandwidth of the FM carrier 4. For step (9) calculated the frequency component, the amplitude, average power for each sideband pairs, then calculate the bandwidth
