基于MATLAB的语音信号分析及滤波(DSP课程设计说明书) 设计题目、内容及要求 课程设计的题目：基于MATLAB的语音信号分析及滤波。 课程设计的内容：录制一段个人自己的语音信号,并对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采用窗函数法和双线性变换设计滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前-Design based on MATLAB voice signal analysis and filtering (DSP curriculum design manual) subject, content and requirements for curriculum design Title: MATLAB-based analysis and filtering of the voice signal. Curriculum design: recording period of the individual' s own voice signal, and the recorded signal is sampled　draw the sampled speech signal time-domain waveform and frequency spectrum　to set the filter performance, using a window function method and double transform the design of filters, and draw the frequency response of the filter　signal acquisition, filtering, and then use the filter of their own design to draw the waveform and spectrum of the filtered signals in time domain and filtering
