. Write a function in MATLAB to generate the following band-limited message signal 2t 2t 2t m(t) = 2sine(-) + sinc +1) + sine(-) Ta Ta Ta-1 (a) Write a function to generate a DSB-SC for t E (-0.04,0.04). The frequency of the carrier is 300 Hz, and Ta 0.02. Plot the original message and DSB-SC signals in both time and frequency domain (b) Demodulate the DSBC-SC signal using both the coherent and carrier re-insertion methods. Show spectrum of the signal produce at each stage of the demodulate process, comment on the results. (c) Repeat (a), but this time generate an SSB signal using the phasing method and the filtering approach. Show the spectra produced using both approaches. Please do this for both the upper and lower side band. (d) Demodulate the SSB signal using both he coherent and carrier re-insertion method. Plot the spectrum of the resulting signal generated at each stage of the demodu lation process. (e) Compare the performance of the four bandwidth required to transmit the message
