# Z Transform and LTI System Properties Study Guide

## Introduction

This page will go over some of my conclusions about properties of the z-transform and discuss some examples of how they may be used to draw conclusions about LTI systems. This topic assumes some basic knowledge of the z-transform and signal processing, however some definitions are provided below as a refresher or for reference. The information provided is intended to clarify or expand on some of the z-transform properties presented in class.

## definitions

z-transform: $X(z) = \sum_{n=-\infty}^{\infty} x[n]z^{-n}$

right sided: $x[n]$ such that $x[n] = 0$ ∀ n < n0
