Building Simulink Model of Frequency Modulation and Demodulation o The frequency modulator and demodulator structures are as explained below. In the first model, you are provided a FM structure.. In the second model, you will observe the frequency variations with respect to the input signal's waveform. In this case, you will use the modulator and demodulator blocks provided by Simulink.
