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，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号-The individual' s own record a voice signal, and the recorded signal is sampled draw sampled

S变换在Matlab中对于信号处理方面的应用-S transform in Matlab for signal processing applications

Ｓ变换，ＭＡＴＬＡＢ 多分辨率分析可以从两个角度引入,函数空间的剖分和理想滤波器组,前者是首先提出的,数学上比较严谨,结论也比较全面。-S transform, MATLAB Multi-resolution analysis can be introduced two Angle, function space subdivision and the ideal filter group, the former is first proposed, math is rigorous
