说明:  先采集一单声道音频信号(.wav)并用WAVREAD文件采样读取,并对其进行频谱分析。分别用窗函数法和双线性变换法设计低通、高通、带通三种FIR滤波器和IIR滤波器。用M文件使信号通过滤波器并对输出信号进行时域和频域分析。
(First acquisition of a mono audio signal (. Wav) files with sampling WAVREAD read, and their spectral analysis. Window function, respectively and the design of bilinear transform low-pass, high pass, band-pass FIR filters and IIR three filters. M document with the signal through the filter and the output signal in time domain and frequency domain analysis.)
