Frequency Modulation(Simulation experiment)
 .
.
1)A frequency-modulated signal which has a resting frequency of 103.000 MHz and whose lowest frequency is 102.993 MHz when modulated by a particular wave. The highest frequency reached by the FM wave is 
  
2)For a FM signal having a carrier swing of 160 KHz when the modulating signal has the frequency of 8 KHz. The modulation index of the FM signal is 
  
3)The carrier deviation necessary to provide the percentage modulation of 85% in the 88-108MHz FM broadcast band is 
  
4)If an 8 MHz band were considered for use with the same standards that apply to the 88-108 MHz FM broadcast band (i.e., each station using 150 KHz for the signal and a guard band of 25 KHz above and below with only alternate channels being used), the number of FM stations that could be accommodated is 
  
5)A narrow-band FM signal which is generated by a 6 KHz signal modulating a 100 MHz carrier. The bandwidth of the narrow FM signal is 
  
6)Two signals of 2 GHz and 4 GHz frequency modulated on the same carrier of 12 GHz. Find the ratio of frequency deviations if the bandwidths of both are equal. 
  
7)Which one of the following can demodulate an FM signal?
