利用matlab实现语音输入、8bit PCM音频截短、滤波输出。用于将大于8bit的PCM语音截短为8bit的PCM语音。(Matlab realize the use of voice input, 8bit PCM audio truncated, filter output. Will be greater than for the PCM voice 8bit to 8bit truncated the PCM voice.)

是数学竞赛的往年考题！！希望对大家有用！！(Mathematics exam in previous years the competition! ! Hope it useful! !)

THP算法的MATLAB程序，可以给初学者一个好的教学(THP algorithm MATLAB procedures, can give a good teaching beginners)

FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。 (FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

为了平衡粒子群算法的全局搜索能力和改良局部能力，采用非线性的动态惯性权重即自适应权重法。给出一个用自适应权重的粒子群算法求多元复杂函数的最小值实例。(To balance the PSO global search capability and improved local capacity, the use of non-linear dynamic adaptive inertia weight that the weighting method. Gives an adaptive weights PSO seeking the minimum of multiple instances of complex functions.)

matlab仿真模型求解系统调节时间，上升时间以及超调量等(matlab simulation model to solve the system settling time, rise time and overshoot, etc.)

说明：  三维重建，使用matlab编写的，效果还可以。(3D reconstruction, using MATLAB, the effect is OK.)
