Message signal= sin(2pi fo t)
Where fo=20hz and fs=700hz
a). Develop a function with the name myAMmod to modulate the message signal. Use a carrier frequency fc=200hz. Plot the magnitude spectrum of the message signal and the modulated signal and explain the difference between them. You may not MATLAB syntax; ammod.
b). Develop a function with the name myamDmod to demodlate the output of part a). You may not us MATLAB syntax; amdemo.
c). Plot the frequency spectrum of the demodulated signal. Compare it with the original message signal
d). plot the demodulated signal in the time domain. Compare it with the orginal message signal.
