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.
1. Generate a baseband signal as show below. Plot the baseband
signal in time domain and frequency domain. 2. Create an FM process and
plot the modulated signal in time and frequency domain.
