Amplitude and Frequency Modulations
 

Amplitude and Frequency Modulations problem 20


A carrier wave is frequency modulated.


  • Describe what is meant by frequency modulation.


  • The sinusoidal carrier wave has a frequency of and an amplitude of . The carrier wave is frequency modulated by a sinusoidal signal of frequency and amplitude . The frequency deviation of the carrier wave is . Determine, for the frequency-modulated carrier wave,


    • the amplitude,


    • the minimum frequency,


    • the maximum frequency,


    • the number of times per second that the frequency changes from its minimum value to its maximum value and then back to the minimum value
