Hi!
How can I find inverse z transform of \(X(z)=\frac{5}{(z-2)^{2}}\) ? It is known that x[n] is causal.

 

You need to show YOUR best attempt to solve YOUR homework problem.

You might consider what property of the Z-transform 1/(z^2) represents and what property of the Z-transform (z-2) represents.

 

I know that inverse z transform of 1/(z^k) is delta(n-k).
Ok, here is what I have done:



I stuck there.

 

Hi,

Here is a cleaned up image. It's a bit easier to read and takes less bytes.

 

Here is Latex version:
