说明：  c source Code for arthmetic

主要用于扩展频谱脉冲幅度调制当中波形的产生(Mainly used for spread spectrum pulse amplitude modulation waveforms which have)

说明：  电子数字秒表（1． 开始时，显示“00”，第1次按下SP1后就开始计时。 （2． 第2次按SP1后，计时停止。 （3． 第3次按SP1后，计时归零 (Electronic digital stopwatch (1. Beginning to show &quot 00&quot , 1st time by pressing start after SP1. (2. The first two sub-prime mortgage SP1, the time to stop. (3. Article 3 times by SP1, the time go Zero)

说明：   1.录制一段自己的语音信号，并对录制的信号进行采样； 2.画出采样后的语音信号的时域波形和频谱图； 3.给定滤波器的性能指标，采用窗函数法和双线性变换法设计滤波器， 并划出滤波器的频域响应； 4.用该滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱， 并对滤波前后的信号进行对比，分析信号的变化； 5.回放语音信号； 6.设计一个信号处理系统界面(1. Recorded their own voice for some signal, and recording the signal sampling 2. Draw samples of the voice signal after the time-domain waveform and frequency spectrum 3. Given filter performance indicators, using a window function method and dual- Design of linear transformation filters, and draw the filter frequency response 4. to use the filters on the collected signal filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes 5. playback voice signal 6. to design a signal processing system interface)

MATLAB 图像处理命令 相关命令： bwarea, bweuler, bwfill 功能： 增加或降低颜色映像表的亮度(matlab语句 ．applylut bestblk 4．brighten 功能： 增加或降低颜色映像表的亮度。)

该代码是基于背景建模的粒子滤波算法程序，代码可以运行，且效果很好。(The code is the procedure of particle filter algorithm based on background modeling, the code can be run, and the effect is very good. )

matlab和simulink的进阶书籍，适合控制类专业的学生(Advanced matlab and simulink books suitable for the control class professional students)

基于MATLAB的圆检测的图像处理，用到了最小二乘法，和霍夫变换(circle detection)

该文档主要实现matlab中的msk调制解调功能，广泛运用于现代数字通信中(The document is mainly achieved in the matlab msk modulation and demodulation functions, widely used in modern digital communications)
