In frequency Modulation (FM), the instantaneous frequency of a
sinusoidal carrier wave will be modified proportionally to the
variation of amplitude of the message signal. Use Matlab to build
an FM modulation and demodulation process. The FM coefficient is
Kf=80, and the carrier frequency is 300Hz.
