说明：   1.录制一段自己的语音信号，并对录制的信号进行采样； 2.画出采样后的语音信号的时域波形和频谱图； 3.给定滤波器的性能指标，采用窗函数法和双线性变换法设计滤波器， 并划出滤波器的频域响应； 4.用该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； 5.回放语音信号； 6.设计一个信号处理系统界面(1. Recorded their own voice for some signal, and recording the signal sampling 2. Draw samples of the voice signal after the time-domain waveform and frequency spectrum 3. Given filter performance indicators, using a window function method and dual- Design of linear transformation filters, and draw the filter frequency response 4. to use the filters on the collected signal filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes 5. playback voice signal 6. to design a signal processing system interface)
