这个是本人自己做的一个matlab程序,希望大家可以能用到,2.4.6....32变为灰度(this is the doing of a Matlab procedures in the hope that we can use to be, 2.4.6 .... 32 into gray)

气候分析中检验突变的经典程序，如滑动t检验，cv，滑动f检验等(Climate Analysis classic mutation testing procedures, such as sliding t test, cv, sliding f inspection)

1. 给一段原始的语音信号（可以是自己录制的一段语音），加上一频率为3.8kHz的高频余弦噪声和频率为3.6kHz的高频正弦噪声（幅度自己可以选择），用窗函数设计一滤波器（要求最小阻带衰减为50dB）对加噪后的语音信号进行滤波，画出滤波器的频率响应曲线，画出滤波前后的时域图和频谱图。 需要用到的函数： fir1 用窗函数设计FIR滤波器的函数 2. 用GUI设计一界面（如图1所示）完成如下功能： 1） 输入一语音信号，画出语音信号的时域图和频谱图； 2） 对语音信号加噪处理，画出加噪后的时域图和频谱图； 3） 给定滤波器的性能指标，采用几种不同的方法设计滤波器对加噪信后进行滤波，画出各滤波器的频率响应曲线，画出滤波后的时域图和频谱图。 (1. to some of the original speech signal (which can be a voice you record yourself), plus a cosine frequency of 3.8kHz frequency noise and frequency of 3.6kHz frequency sinusoidal noise (in the range that they can choose), with a window function to design a filter (requires a minimum stop band attenuation is 50dB) after adding noise to the speech signal is filtered, the filter frequency response curve to draw, draw diagrams and time-domain spectrum before and after filtering. Need to use the function: function fir1 with window function design FIR filter design 2. Using a GUI interface (Figure 1) complete the following functions: 1) an input speech signal, the speech signal in the time domain to draw graphs and spectrum 2) adding noise to the speech signal processing, draw diagrams and time-domain plus noise spectrum after 3) to set the filter performance, using several different methods designed to filter letter after adding noise filtering, draw the frequency response curve of each )

关于Vega Prime的12篇期刊论文，涉及VP多场景切换、坐标系、多通道、飞行视景仿真等问题，有相当的参考价值。(About Vega Prime' s 12 journal articles, and more scenes involving VP switching coordinates, multi-channel, flight visual simulation and other issues, there is considerable reference value.)

此例程可以用来进行希尔伯特变换，得到包络谱，利用差分公式得到瞬时频率(This routine can be used to carry out Hilbert transform, obtain envelope spectrum, and obtain instantaneous frequency by using difference formula)
