The input-output relationship of a causal stable LTI system is given as
y[n] = α y[n - 1] + β x[n]
If the impulse response h[n] of this system satisfies the condition Σh[n] = 2 (from n=0 to ∞), the relationship between α and β is
y[n] = α y[n - 1] + β x[n]
If the impulse response h[n] of this system satisfies the condition Σh[n] = 2 (from n=0 to ∞), the relationship between α and β is
Correct : a
