Inverse Z Transform
Overview
- The purpose of this page is to...
- 1. Define the Z Transform and Inverse Z Transform
- 2. Provide Example Problems of the Inverse Z Transform
1. Definitions
- Z Transform
$ X(z)=\mathcal{L}(x[n])=\sum_{n=-\infty}^{\infty}x[n]z^{-n} $
- Inverse Z Transform
$ x[n]=\mathcal{L}^{-1}(X(z))=\frac{1}{2\pi j}\oint_{c}X(z)z^{n-1}dz $
