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

3. We modulate a 100 Hz signal with a 1000 Hz signal:
cos 200лt
p(t)
We then demodulate the signal as follows:
X
X
cos 2000 t
cos 2000 t
p(t)
BPF
d (t)
Find the spectra of the modulated signal (t) and the demodulated
signal d (t). Indicate magnitudes and frequencies.
Find the average power in both the modulated signal and the demodulated
signal.
