Web程序1:用MATLAB对原始语音信号进行分析，画出它的时域波形和频谱. fs=8000; %语音信号采样频率为8000. x1=wavread('pb8k.wav'); WebThis means that the required band-reject filter is. h b r, L H [ n] = h l p f, L [ n] + h h p f, H [ n]. Hence, a band-reject filter can be created from a low-pass and a high-pass filter with appropriate cutoff frequencies by adding the two filters. The example band-reject filter of Figure 2 has f L = 0.1 and f H = 0.4, with again b = 0.08.

In matlab's filtfilt, it is 3* (max (len (a), len (b)) - 1), and in scipy's filtfilt, it is 3*max (len (a), len (b)). Therefore, I modified the padlen when invoking filtfilt in Python.
