Description: DSP程序里IIR滤波结果跟MATLAB仿真结果相差很大是为什么?各位老兄: 我最近利用TI库函数里IIR滤波程序对一组数据进行滤波,IIR系数利用TI公司所提供的eziir.m(matlab程序)程序获得,在matlab里利用相同的系数对相同的数据进行滤波-DSP program results IIR filter with MATLAB simulation results are very different and why? You man: I have the use of library functions in TI procedures IIR filter to a group of data filtering, IIR coefficients provided by the use of TI' s eziir.m (matlab program ) procedures in matlab using the same coefficient in the same data filtering

Description: 用一个2阶的AR模型产生一平稳的随机过程s(n)。
其中， ， ， 可任意选定。
再产生一方差为 的白噪声 。接收信号为
，
要求对接收信号进行维纳滤波，输出信号为 。
1， 给定维纳滤波器的长度M，考察代价和函数与SNR之间的关系。
2， 给定SNR,考察代价函数与信噪比之间的关系。
3， 做一步预测，代价函数随滤波器的长度和信噪比的变化关系。
-With a 2-order AR model to generate a stationary random process s (n). Among them,,, can be arbitrarily selected. Accrue to the white noise variance. Received signal, the received signal requires filtering, the output signal. 1, given the length of the Wiener filter M, investigation costs and the relationship between function and SNR. 2, for a given SNR, the cost function and examine the relationship between signal to noise ratio. 3, do step prediction, the cost function with the filter length and variation of signal to noise ratio.

Description: 这是哈尔滨工业大学数字信号处理课的课程设计作业，利用窗函数涉及滤波器分别对自己设定的测试信号和老师给定的连续频谱信号进行滤波。
我编写时先后在同一个M文件中写了很多的画图语句，如果直接F5运行，它们会互相覆盖，使用时请将需要的绘图代码复制到命令行中重新运行。(This is the course design assignment of Digital Signal Processing Course of Harbin University of Technology. The window function is used to filter the test signal set by yourself and the continuous spectrum signal given by the teacher.)
