摘要
分析了时域卷积运算和频域加权算法的物理意义,并利用MATLAB的声音处理函数作为数据接口,利用多媒体播放器作为交互界面,利用MATLAB的FDATool作为滤波器设计工具,设计了一组语音信号滤波实验,目的在于:通过对比滤波前后的语音效果来加深对数字信号处理的认识.
This paper analyzes the physical significance of the time domain convolution operation and the frequency domain weight algorithm. And by using the MATLAB sound processing function as the data connection, the multimedia players as the interactive contact surface, the MATLAB FDATool as the filter design tool, designs a group of experiments for audio signal filter with the purpose of strengthening the understanding of the digital signal processing by comparing the change of the audio effect before and after the filter.
