The difference equation of a LTI system is

$y(n)=x(n)+x(n-1)$

If the corresponding unit impulse response is $h(n)$ find using Matlab the impulse response $h_{10}(n)$ of $10$ cascaded units of the above LTI system. Cascading refers to the connection of the output of the k$-$th LTI system to the input of the $k+1-$th LTI system. Also find the FFT of both $h(n)$ and $h_{10}(n)$ in both magnitude and phase. You may use the inbuilt $)$ function in Matlab for this part of the project.
