a) Determine whether the discrete time system which has an output $y[n]=2?x[n]$ over the interval $0<=n<=10$ is linear or not by determining the response $yl[n$ ] to the input signal $×1[n]=sin((2?pi/10)?n)$ and the response $y2[n]$ to the input signal $x2[n]=cos((2?pi/10)?n)$ Determine the response $y3[n]$ to the input signal $x3[n]=x1[n]+x2[n]$ and compare it with $y4[n]=y1[n]+y2[n]$. Plot (using stem) in one graph all the input signals and their corresponding output signals. Use the disp command to output whether the system has 'outputs consistent with a linear system ' or 'not linear'.
