信号与系统，信号与系统课设的信号加入噪声以及滤波(Signals and Systems, Signals and Systems course set signal to noise and filtering)

主板故障的确定，一般通过逐步拔除或替换主板所连接的板卡（内存、显卡等），先排除这些配件可能出现的问题后就可以把目标锁定在主板上(Motherboard fault is fixed, or replace the motherboard through the gradual removal of the connected board (memory, graphics, etc.), first rule out possible problems of these accessories can be targeted after the motherboard)

关于信号处理的十个matlab程序，很经典值得一看，信不信由你，下来看看可以改变你的很多思路(About ten MATLAB for signal processing programs, a classic worth seeing, believe it or not is up to you, can change many of your ideas )

函数功能:本函数将完成随机选择LSB的信息隐藏,载体选用BMP图，和提取隐秘与LSB上的秘密消息(Function: This function will be completed randomly selected LSB information hiding a secret message on the carrier selected BMP map, and extract hidden LSB)

ant colony optimization

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

这是一个关于matlab的课件，里面有几个小例子，可供参考！(This is a study on matlab courseware, which has several small example is available for reference!)
