Wavelet-Analysis
- 对于非平稳信号的分析不能依靠傅里叶变换，但可以采用时频分析的方法，其中加窗傅里叶变换是最简单的一种。但是，它有很大的局限性：当基本窗函数一旦取定，窗口的时窗宽度和频窗宽度就固定了，不会随时域和频域的位移而变化。-For non-stationary signal analysis can not rely on Fourier transform, but you can use time-frequency analysis method, in which the windowed Four

haimingchuang
- 海明窗 语音信号一般在10ms到30ms之间，我们可以把它看成是平稳的。为了处理语音信号，我们要对语音信号进行加窗，也就是一次仅处理窗中的数据。因为实际的语音信号是很长的，我们不能也不必对非常长的数据进行一次性处理。明智的解决办法就是每次取一段数据，进行分析，然后再取下一段数据，再进行分析。 -Hamming window voice signal is generally between 10ms to 30ms, we can see it as is stationary. To h
