| 摘 要： | 滤波器设计是数字信号处理的重要组成部分。在计算机中录入一段语音信号，通过Matlab对语音信号进行时频变换与分析，同时构造一固定频率的干扰信号，对两个信号进行合成，设计一个数字滤波器，对含噪的的语音信号进行滤波处理，在时域和频域中对信号进行分析比较。

| Abstract: | The filter design is one of the most important parts of the digital signal processing.The paper transforms and analyzes the speech signal in time and frequency area through Matlab with recording one speech signal in a computer.Meanwhile it makes one fixed frequency interference signal,combines two signals and designs a digital filter,then it filters the noise and analyzes the signal in time and frequency area. |
