Question

Please help me with this problem 2 with steps by steps

Answer 1

Here is a complete solution

Here x_1 (n) = 1 3 2 x_2 (n) = L L 1 x_2 (n - 1) = 1 1 1 x_2 (n - 2) = 0 1 1 1 2 x_2 (n - 2) = 0 2 2 2 - 2x_2 (n - 2) + x_1 (n) = 1 1 0 - 2 so x_3 (n) = x_1 (n) - 2 x_2 (n - 2) so, y_3 (n) = y_1 (n) - 2 y_2 (n - 2) y_1 (n) = 1 1 2 y_2 (n) = -2 1 y_2 (n - 1) = -2 1 y_2 (n - 2) = - 2 1 1 2 y_2 (n - 2) = -4 2 2 y: (n) - 2y_2 (n - 2) = 5 - 1 0 = y_3 (n)
