$3-$Write matlab code that shows the fim modulation and demodulation lat the signal massage amplitude $=4v$ and the amplitude carrier $=2v$ and the frequency of massage signal is $50H$ and the frequency of carrier is $700H$ and the nequest rate frequency is $10000H$ find the code result and find the table:

$\backslash$table$[[$Vm$,$F max,F min,fd$,\backslash$table$[[$Modulation$],[$index$]],$Band width,$\backslash$table$[[$Demodulation$],[$signal frequency$]]],[,,,,,,]]$
