Please write matlab code with comments. Frequency ModulationThe message signalsinc(100f) |t| < tom(t) =otherwisefrequency modulates the carrier c(t) = cos(2nfet), when f. = 250 Hz and to = 0.1.The frequency-deviation constant is kf = 100. Therefore, the frequency-modulatedsignal isu(t) = cos (2nft + 2nks m(t)dt).1. Plot the message signal and its integral on two separate graphs. The samplinginterval is t, = 0.0001.2. Plot the FM signal u(t).3. Use MATLAB’s Fourier-transform routine to compute and plot the spectra ofm(t) and u(t) on separate graphs.4. Determine the modulation index, the bandwidth, and the range of the instanta-neous frequency of u (t).5. Demodulate the FM signal u(t) to obtain the message signal and compare theresult with the original message signal. The FM signal can be demodulated byfirst finding the phase of u (t), i.e., the integral of m(t), which can be differenti-ated and divided by 2nkf to yield m(t). Use the MATLAB function unwrap.mto undo the effect of 2T-phase foldings. Comment on how well the demodulatedmessage signal matches the original message signal m(t).
