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

Q2: An angle-modulated signal with carrier frequency W. = 2n 10° is described
by equation
FEm = 10 cos (W,t + 0.1sin2000nt)
a. Find the power of the modulating signal if the load resistance is R=1.
b. Find frequency deviation.
c. Estimate the B.W of the system.
d. Compute and draw the spectrum for above FM signal.
e. if ß = 1, Compute power of three terms only.
