Question: Suppose the z-transform of x[n] is It is also known that x[n] is a stable sequence. (a) Determine the region of convergence of X(z). (b)

Suppose the z-transform of x[n] is

,10 X(2) = (: - !)(z - })"(z+ })*(2+ })(z+ }) 10

It is also known that x[n] is a stable sequence.

(a) Determine the region of convergence of X(z).

(b) Determine x[n] at n = ? 8.

,10 X(2) = (: - !)(z - })"(z+ })*(2+ })(z+ }) 10
