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.

Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...
