Amplitude and Frequency Modulations
 

Amplitude and Frequency Modulations problem 19


The variation with time of the displacement of an amplitude-modulated (AM) wave is shown in the figure below.




The sinusoidal information signal has frequency .


  • Determine the frequency of the carrier wave.


  • On the axes of the figure below, sketch the frequency spectrum of the modulated wave.
