利用MATLAB实现离散时间系统的时域和频域分析
目的
1.进一步熟悉和掌握通过系统函数H(Z)分析离散时间系统的时域和频域特性；
2.复习如何用MATLAB语言实现离散时间系统的时域和频域分析

内容
1.运用MATLAB指令绘制离散时间系统的零极点图、脉冲响应和频率响应曲线
2.根据系统的零极点图分析该离散系统的稳定性

原理
离散时间系统的系统函数表示式为：XXXXXX
需要注意的是，离散时间系统的系统函数可能有两种形式，一种是分子和分母多项式均按Z的正幂次项排列，另一种是分子和分母多项式均按Z的负幂次项排列。无论采用哪种排列形式，分子和分母多项式系数向量的维数一定要相同，不同的要用0补齐，否则Z=0的零点或极点就可能被漏掉。
系统函数H(Z)的零极点分布完全可以决定系统的特性，对离散系统特性的分析具有非常重要的意义。通过对系统函数零极点的分析可以获得离散系统以下几个方面的特征：
1.系统脉冲响应h（n）的时域特性
2.离散系统的稳定性
3.离散系统的频率特性（幅频响应和相频响应）
MATLAB为我们提供了求解这些特性及绘制系统函数零极点图的相关函数，如zplane、impz、freqz等，这些函数的使用方法详见本书6.5和6.6节的内容。

执行该程序得到所要求的图形，如下图所示。
从图1的零极点图可以看到，该系统函数的极点都在单位圆内，所以该系统为稳定的系统。

任务
1.已知离散系统的系统函数XX，试利用MATLAB分析该系统的时域和频域特性。要求：在一个窗口中分别画出系统的零极点图、脉冲响应、幅频和相频特性，并判断系统的稳定性。
2.已知某离散时间系统的框图如图2所示，试利用MATLAB分析该系统的频率特性。要求：在一个窗口中分别画出系统的零极点图、相频特性曲线、0-π和0-2π区间的幅频特性，并分析该系统的稳定性及其所完成的功能。

思考题
如果想显示0-π和0-2π区间上的频率特性以观察离散时间系统频响的周期性，应如何调整你的MATLAB指令？

忘了说哈，谢绝G歌、B度、Y虎、金山等等机器的翻译啦，节约大家的时间嘛！

MATLAB realize the use of time domain and frequency domain analysis
Purpose
1further familiarize and master through the system H function ( Z ) analysis of discrete time system in time domain and frequency domain properties;
A 2review of how to use MATLAB language implementation of discrete time system in time domain and frequency domain analysis

Principle
Discrete time system function expression for: XXXXXX
Note that, discrete time system function may have two forms, one kind is the numerator and denominator polynomials according to Z positive power item arrangement, the other is the numerator and denominator polynomials are Z negative power time arrangement. Either arrangement, the molecule and the denominator polynomial coefficient vector dimension must be the same, different to0to complete, or Z = 0zeros or poles may be missed.
System function H ( Z ) of the zero and pole distribution can decide the system characteristics, the discrete system characteristics analysis has the very important significance. Through analyzing the system function pole-zero analysis can be obtained from discrete system for the feature of the following respects:
1 the system impulse response H ( n ) in the time domain characteristics
2stability of discrete systems
3discrete system frequency characteristics ( amplitude frequency response and phase frequency response. )
MATLAB provides us with solving these characteristics and rendering system function pole zero plot of the correlation function, such as zplane, impz, freqz and so on, the use of these functions method for book6.5 and6.6section.
The implementation of the procedures are required graphic, as shown below.
From the graph 1pole-zero diagram can be seen, the system function poles are inside the unit circle, so the system stable system.
Task
The 1known discrete system function XX, by MATLAB analysis the system in time domain and frequency domain properties. Requirements : a window to respectively draw system pole zero plot, impulse response, the amplitude frequency and phase frequency characteristics, and to judge the stability of the system.
