Whether x [n] input signal and impulse response. Find Y (z) and y [n] using the Z transformation and the formula Y (z) = X (z) H (z).

x (n) = u [n]; h [n] = (0.5) ^ n u [n]; where X (z) = z / (z-1); H (z) = z / (z-0.5)

Which of the following is the y [n] signal?

The output of the system is expressed by the difference equation and

y (n) -5y (n-1) = 2x (n) -4x (n-1)
