Question: Consider a right-sided sequence x[n] with z-transform, In section 3.3 we considered the determination of x[n] by carrying out a partial fraction expansion, with X(z)

Consider a right-sided sequence x[n] with z-transform,

1 X(2) = %3D (1 - az-)(1 bz-1) (z - a)(z -

In section 3.3 we considered the determination of x[n] by carrying out a partial fraction expansion, with X(z) considered as a ratio of polynomials in z^?1. Carry out a partial fraction expansion of X(z), considered as a ratio of polynomials in z, and determine x[n] from this expansion.

1 X(2) = %3D (1 - az-)(1 bz-1) (z - a)(z - b)"
