本实验隶属现代数字信号处理,涉及到谱估计和谱分解,对学习数字信号的现代处理方法帮组很大。系统辨识实验实现:输入为功率为1(方差为1)的白噪声信号,通过一个线性移不变(LSI)系统,采用功率谱分析方法实现系统辨识对一个LSI系统进行辨识,并比较最后辨识出的系统与原系统的差别,分别显示出来。
(Experimental realization of system identification: input power of 1 (variance 1) of the white noise signal through a linear shift invariant (LSI) system, using power spectral analysis method of system identification of an LSI system identification, and compare the final system and identify the difference between the original system, respectively, is displayed.)
