| 摘 要： | 巴特沃斯数字滤波器是IIR数字滤波器的一种,由于其频率响应在通频带内具有最大限度平坦,因此对音频信号的平滑处理具有较好的效果,是一种应用较为广泛的滤波器.本文基于Matlab设计了巴特沃斯数字低通滤波器,并在Simulink仿真平台下对音频信号进行处理,仿真结果表明所设计滤波器有效地对音频信号进行了处理.

| Abstract: | Digital Butterworth filter is a kind of IIR digital filters.Due to its plain frequency response in passband,the process of smoothing audio signal has better effect.Based on the software-Matlab,this article has designed a digital Butterworth low-pass filter by programming,and applied the audio signal in Simulink platform.The simulation results show that the filter is effective. |
