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

Consider a message signal m(t) = 4 cos (22000t) + 0.5 cos(27500t) to be FM modulated, with
kf = 1000 Hz/Volt. (i) Determine the peak frequency deviation in Hz. (ii) Determine and sketch
the line spectrum for fe = 100 kHz. (Drop all the individual Bessel coefficients below 0.1)
