In this section we like to use Matlab to generate an FM signal
and model the frequency discriminator, similar to the circuit we
completed in the lab. Use the input parameters you used in the
lab.
1- W r i t e Matlab codes to plot the FM modulated signal and
the modulating signal.
2- S h o w (using MATLAB) the frequency spectrum of the FM
modulated signal. Is it consistent with what you saw on the scope?
3- P l o t ( u s i n g M A T L A B ) the output of the Envelop
Detector for different values of R. What happen to the signal? What
is the best choice of RC? Note that in our case we used C= 1uF.
