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)
