Let's have the following signals: x(n)={(2),1,2,1} (Note that (2) is the value of x(n) for n=0) h(n)={(1),2,3,4} (Note that (1) is the value of h(n) form n=0) 1) Perform the linear convolution yL(n)=x(n)h(n) 2) Perform the circular convolution yn(n)=x(n)h(n) 3) Are yL(n)=yn(n)? 4) What's the minimum value of N to be choosed to avoid alyasing ? Give the new expressions of X
