Concept explainers

Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.

Question

Given the amplitude modulated signal: S(t) = cos(2000t) + 4cos(2400rt) + cos(2800nt) the ratio of the power
of the message signal to the power of the carrier is:
Select one:
O a. 0.14
O b. 0.675
O c. 0.22
O d. 0.18
O e. 0.125
