x(n+2) = {2, 1} x(n-1) ={3, 2, 1} 2x(n) = {8, 6, 4, 2} Question: Given a digital signal sequence x(n) = {4, 3, 2, 1} (n=0, 1, 2, 3), list x(n+2), x(n-1), and 2x(n). x(n+2) = {2, 1} x(n-1) ={3, 2, 1} 2x(n) = {8, 6, 4, 2}
Exercise-1: Write a programme in Matlab or C++ to implement the signal representation of the sequence example.
