22.

For the discrete time system of the given figure

y_k - 0.5 y_k_{- 1} - 0.25 y_k_{- 2} = u_k

y_k + 0.5 y_k_{- 1} - 0.25 y_k_{- 2} = u_k

y_k - 0.5 y_k_{- 1} + 0.25 y_k_{- 2} = u_k

y_k + 0.5 y_k_{- 1} + 0.25 y_k_{- 2} = u_k

Answer: Option

Explanation:

u_k + 0.5 y_{k - 1} - 0.25 y_{k - 2} = y_k.
