| Mar 30, 2018 at 14:51 | comment | added | Steve Cox | Why is it guaranteed to be MA? there are stable AR processes. Either way though, if you are talking about BIBO stability, then yes the sum is trivially stable because you can calculate the new bounds. Asymptotic stability also holds because $\lim_{t \to \infty} z_t = \alpha\lim_{t \to \infty} x_t + \beta\lim_{t \to \infty} y_t$ | |
