Amplitude Modulation and Demodulation (Real time experiment)
.
.
1)A 3500 Hz audio tone amplitude modulates a 800 kHz carrier resulting in modulated signal having a percentage modulation of 85%. The highest frequency that appears in the spectra of the modulated signal is 
  

2)In case of tone modulation, the maximum possible power efficiency is 
  

3)The main reason why SSB and DSB modulations do not found acceptance for use in home-type entertainment equipment is 
  

4)An AM signal contains 400 W at its carrier and 64 W each at its sidebands. If the percentage modulation of the AM signal is changed to 50%, the power content of each sideband becomes 
  

5)A 96 KHz bandwidth is required to accommodate eight AM broadcasts simultaneously. The maximum modulating frequency of each station must be limit
