Distribution systems power flow analysis package using Matlab coded

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )

应用背景蒙特卡罗方法（或蒙特卡罗实验）是一种广泛的类的计算算法，依赖于重复随机抽样，以获得数值结果。他们经常使用在物理和数学问题，是最有用的，当它是困难或不可能使用其他数学方法。蒙特卡罗方法主要应用在三个不同的问题类：优化，数值积分，并从一个概率分布的生成。关键技术用蒙特卡罗方法计算了近似值。该项目包含蒙特卡洛功能，以及完整的程序与数字和图。
