Hello i would need some help to compute the Z-inverse transform of:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \frac{1}{z^{2}-1} [/tex] and [tex] \frac{1}{(z-1)(z^{2}-1)} [/tex]

i don,t know if they can be computed using the residue theorem as the inverse in general has the form:

[tex] 2\pi i a(n)=\oint f(z)z^{n-1}dz [/tex] for a curve on complex plane...:grumpy: :grumpy:
