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.

SinusoidalasymmetricPWMmodulatiobased3PhInverter
Static power inverter can be analyzed by means of means of widely available circuit simulation software packages such as MATLAB. However, they are usually modeled a set of real switches, which results in long execution tines and possible convergence problems in the case of complex circuits. This paper proposes different PWM techniques to used in the simulation of three-phase power inverter. The
