Question $2[20$ Marks$]$

The continuous$-$time signal is described below. By using MATLAB, obtain the Fourier transform of the signal, $x()$ and also plot the original signal, $x(t).$ You need to define the suitable value of $t.$

$x(t)=cos(2t)+2cos(2(0\mathrm{.}8)t)+0\mathrm{.}5cos(2(1\mathrm{.}1)t)$

$[$hint: Use fft and fftshift commands in MATLAB$]$
