对具有随机噪声的二阶系统的模型辨识，进行标幺化以后系统的参考模型差分方程为 (7.90) 式中， 为随机噪声。由于神经网络的输出最大为1，所以，被辨识的系统应先标幺化，这里标幺化系数为5。利用图7.5正向建模(并联辨识)结构，神经网络选用3-9-9-1型，即输入层i，隐层j包括2级，输出层k的节点个数分别为3、9、9、1个； (Model identification of two order systems with stochastic noise)

比较两个不同的倒频谱分析方法的一个有限的时间框架的言论,即基于fft算法的传统方法(与框架展开复杂的倒频谱),和一个分析方法基于求解有限阶分子多项式的根的倒频谱和直接计算多项式根的位置。(This MATLAB exercise compares two different methods of cepstrum analysis of a finite duration frame of speech, namely the conventional method based on FFTs (with frame unwrapping for the complex cepstrum), and an analytical method based on solving for the roots of a finite order numerator polynomial and directly computing the cepstrum the locations of the polynomial roots.)
