The pdf program with source code takes as input a file that consists of two columns. The first column has in capital letters BC, TC, NC. BC indicates that the ascii text will be byte compressed. TC indicates that the text will be text compressed and NC indicates that the text will be numerically compressed. The second column will have a text string beginning with and ending with quotes. For BC the text must consist of the numbers 0-9 and letters A-F ( Hex 0-9, A-F). Also, in BC if the length of the string is odd,a zero will be prepended to the string to make it and even number. For TC the text can consist of any of the legal text compress charactors in the pdf417 standard. For NC, the letters 0-9 are allowed in the text. -The pdf program with source code takes as input a file that consists of two columns. The first column has in capital letters BC, TC, NC.

my_noise文件是已知信号方差，加入信号噪声，可以加入高斯噪声，淑盐噪声,等其他噪声十分有用 其他两个函数时加入噪声信噪比SNR,但是有一点,这种方法并不准确,不能保证加入噪声信噪比为SNR,实际测试中可以看出,但是可以加入相同的信噪比的噪声-my_noise document is known to signal variance, by adding signal noise, Gaussian noise can be added, suk salt noise, noise, and other very useful function when the other two noise signal to noise ratio SNR, but there is one point, this method is not accurate , can not be guaranteed by adding the noise signal to noise ratio for the SNR, the actual test can be seen, but can join the same noise signal to noise ratio

It is a window mash viewer sample application. Its really nice. Please try it.

这是一个简单的画图程序，能实现画直线与普通画笔一样的画图功能，并能对它们进行任意的裁剪，本人水平有限，程序必存在许多不足，望高人们能多加指点。-This is a simple drawing program, able to draw straight lines with the same brush ordinary drawing capabilities and their arbitrary cut, I limited, and certainly there are many procedures inadequate, and hopes people will be more high guidance.

为了将零件固定在PCB上面，我们将它们的接脚直接焊在布线上。在最基本的PCB（单面板）上，零件都集中在其中一面，导线则都集中在另一面。这么一来我们就需要在板子上打洞，这样接脚才能穿过板子到另一面，所以零件的接脚是焊在另一面上的。因为如此，PCB的正反面分别被称为零件面（Component Side）与焊接面（Solder Side）。-parts to be fixed above the PCB, we will take their feet welded directly on the wiring. At its most basic PCB (single-panel), parts of which are concentrated in the side, wire were concentrated on the other side. Suppose we need burrows on the board, then through the legs of another plank, then parts of the legs is another welding in the face. Because of this, the PCB is negative components were known as surface (Component Side) and the welding surface (Solder Side).
