- 1)选择一个语音信号作为分析对象,或录制一段语音信号; 2)对语音信号进行采样,画出采样前后语音信号的时域波形和频谱图; 3)利用MATLAB中的随机函数产生噪声加入到语音信号中,使语音信号被污染,然后进行频谱分析; 4)设计用于处理该语音信号的数字滤波器,给出滤波器的性能指标,画出滤波器的频率响应; 5)对被噪声污染的语音信号进行滤波,画出滤波前后信号的时域波形和频谱,并对滤波前后的信号进行比较和分析; 6)回放各步骤的语音信号,给出相应处理程序及运行结果分析。-1) Select a voi

- Block-based random image sampling is coupled with a projectiondriven compressed-sensing recovery that encourages sparsity in the domain of directional transforms simultaneously with a smooth reconstructed image. Both contourlets as well as comp
