| 摘 要： | 以FIR数字高通滤波器为例,详细分析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FDA-Tool作为滤波器设计工具,设计一组语音高通滤波器,通过对比滤波前后的语音效果,可加深对数字信号处理的认识。

| Abstract: | The physical significance of the convoluting in time domain and the weighting in frequency domain is analyzed in detail by using the digital high pass filter as the exemplification.And by taking the MATLAB sound processing function as the data connection,the multimedia players as the interactive contact surface,the FDATool of MATLAB as the filter design tool,a group of experiments for audio high pass filter is designed.The understanding of the digital signal processing could be strengthened by comparing the change of the audio effect before and after the filter. |
