Matlab-spectrumananalysis
该文给出了一种利用matlab系统实现频谱分析与显示的方法。该方法对语音信号进行基于FFT的短时频谱分析,频谱图的伪彩色映射及显示。(This paper presents a system implementation using matlab spectrum analysis and display methods. The method is based on the speech signal short-time FFT spectrum analysis, spectrum and display pseudo-color mapping.)

(1) 分别采集一段浊音和清音语音信号(是你自己说的),采样率为8KHZ,量化精度为16比特线性码;
(2) 分析帧长取为30ms(或10ms~50ms);
(3) 根据语音信号倒谱分析和LPC谱分析的编程流程图(图2.1、图2.2)编制浊音语音信号谱分析的matlab程序,上机调试给出相应波形,并根据图形,观察共振峰情况;
(4) 将语音信号换为清音语音,运行程序,与浊音语音的运行结果进行比较,并得出结论。
(5) 在LPC谱分析中,改变阶数p (p分别等于4、8、12、40)时,观察对谱包络的影响,并与信号谱(DFT谱)进行比较。

snowflake
对一个等边三角形,每条边按照Koch曲线的方式进行迭代,产生的分形图称为Koch雪花。编制程序绘制出它的图形,并计算Koch雪花的面积,以及它的分形维数(An equilateral triangle, each edge iterations, in accordance with the manner of the Koch curve generated fractal images is known as the Koch snowflake. Programmed to draw its graphics, and calculate the area of the Koch snowflake, and its fractal dimension)
