摘　　要：z变换是分析离散系统的一个重要工具。本研究介绍z变换三维图的生成方法,探讨使用z变换三维图可视化方式理解离散系统的频域特性,通过电容放电电路、全通系统和梳状滤波器三个实例进一步展示z变换三维图在离散系统分析中的应用。实验结果表明,z变换三维图有助于更全面地理解离散系统的特性。The z-transform is an important tool for analyzing discrete systems.We propose a generation method of z-transform three-dimensional diagrams.The z-transformed 3D diagrams is explored to understand the characteristics of discrete systems and further shown in the analysis of discrete system through three examples of capacitor discharge circuit,all-pass system and comb filter.The experimental results demonstrate that the z-transform three-dimensional diagrams contribute to a more comprehensive understanding of the features of discrete systems.
