Methods to Find Inverse Z-Transform When the analysis is needed in discrete format, we convert the frequency domain signal back into discrete format through inverse Z-transformation. We follow the following four ways to determine the inverse Z-transformation.

May 19, 2020 · This answer is useful. 1. This answer is not useful. Show activity on this post. HINT: Your partial fraction expansion is wrong; you should always check it by recombining the factors. The correct expansion is. (1) X ( z) = z − 1 − 1 2 ( 1 − 1 2 z − 1) 2 = 3 2 ( 1 − 1 2 z − 1) 2 − 2 ( 1 − 1 2 z − 1) You should try to derive this result yourself.
