LC 低通巴特沃斯无源滤波器设计 根据给出的参数值自动计算LC 取值(Butterworth passive LC low-pass filter design parameters according to the given value automatically calculated LC)

是一个规范matlab编程的教程。从网站上截取的。读者可以通过这个文章规范自己的代码编写(Is a norm matlab programming tutorials. Intercepted from the site. Through this article, readers can standardize their own coding)

说明：  由有经验的工程师编写,gps躁声信号的生成,很好的.(by experienced engineers prepared a GPS signal to the impatient generation, very good.)

用matlab语言，实现双边带抑制载波调幅（DSB-SC）信号，并绘制出图(Matlab language used to achieve double sideband suppressed carrier amplitude modulation (DSB-SC) signal, and draw a map)

本压缩文件包括对线性量级，对数量级和指数量级三种AGC方案的仿真，并包括msk信号通过agc回路的一个仿真文件，附带详细的仿真报告(this zip file includes 3 matlab file simulating 3 agc method（linear，log，and exponential).In addition, this file includes an simulation file of msk signal passing through agc loop.An simulation paper is included, too.)

说明：  S 函数使用及应用举例，对涉及到simulink里s函数的应用有详细的解释(The use and application of S function, for example, relating to the simulink function in the application of s has a detailed explanation)

一种可以用来进行图像分超分辨重建的方法，用小波做的(super resolution)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

对图像加入某种噪声，然后通过某种去噪手段再滤除噪声(Adding some noise on the image, and then through some means of re-noising filter noise)
