File to Plot 8 channels in Matlab using data from the USB captured into a TXT file. (it makes the 8 different plots)

说明：  里面有经典的周期图法程序，还有改进的周期图法的程序，形成对比(There are classical periodogram program, as well as improved program cycle diagram method, in contrast to)

本程序用Matlab实现了八皇后问题的所有解，用到了递归的编程思想(The procedures used Matlab eight queens problem all the solutions use recursive programming ideas)

在matlab下开发的，实现信号的仿真和模拟。有需要的可以参考一下(Signal simulation and simulation.)

Abstract—Several algorithms have been developed for tracking formant frequency trajectories of speech signals, however most of these algorithms are either not robust in real-life noise environments or are not suitable for real-time implementation. The algorithm presented in this paper obtains formant frequency estimates voiced segments of continuous speech by using a time-varying adaptive filterbank to track individual formant frequencies. The formant tracker incorporates an adaptive voicing detector and a gender detector for formant extraction continuous speech, for both male and female speakers. The algorithm has a low signal delay and provides smooth and accurate estimates for the first four formant frequencies at moderate and high signal-to-noise ratios. Thorough testing of the algorithm has shown that it is robust over a wide range of signal-to-noise ratios for various types of background noises.

用来模拟粒子运动的。此元胞自动机需要 一种不同类型的元胞的邻居。此元胞的邻居时刻变化，因此某一个方向运动趋势， 将继续在同一个方向。换言之，此规则保存势头，这是基础的动力仿真。这种邻 居通常被称为 margolis邻居并且这种邻居通常由重叠的 2x2 块的元胞构成。在下 面的表格中，偶数步长时左上方 4 元胞为邻居关系，奇数步长时右下的 4 元胞为 邻居关系。某一特定元胞在每一个时间步长都有3 个邻居，但是具体的元胞构成 了邻居的旋转和反复。(Used to simulate the particle movement. The cellular automaton requires a different type of cell neighbors. This moment of change in a neighbor cell, so a certain direction the trend will continue in the same direction. In other words, this rule saved momentum, which is the foundation of the power simulation. This neighborhood is often called a neighbor and this neighbor margolis usually overlapping 2x2 blocks of cellular composition. In the following table, even when the step left four yuan for the neighbor cell, the odd step 4 when the lower right cell for the neighborhood. A particular cell in each time step has three neighbors, but the specific cellular composition of the neighbor s rotation and repeated.)
