In Simulink design a narrow-band frequency modulator according to the block diagram shown below (taken from figure 4.4 of the textbook). - For the modulating wave take a sinusoidal waveform generator that creates: m(t)=Amcos(2fmt);fm=10Hz;Am=1 - For the carrier wave take a sinusoidal waveform generator that creates: c(t)=Accos(2fct);fc=1kHz,Ac=1 - The output should be a narrow-band FM wave described with: s(t)=Accos(2fct)Accos(2fct)sin(2fmt);=0.2 - Design your modulator such that =0.2 (for this you may need to add a gain/attenuation module in your design). - Show an image of your design in Simulink. - Use 3 oscopes to evaluate the signal at: (i) the waveform generator for the modulating wave, (ii) the waveform generator for the carrier wave, and (iii) the output
