瞬态

Namely in high-frequency unit use gradually incisive time resolution and lower frequency resolution, in order to moves the near observation signal quickly to change the part; In low frequency partially has the higher frequency resolution and the lower time resolution, in order to moves the far observation signal slowly to change partially, the wavelet this kind of signal analysing expression characteristic to analyzes the non- steady signal is extremely effective, suits the transient state anomaly very much which smuggles in the survey normal signal and demonstrates its ingredient, therefore by reputation for analysis signal microscope.

即在高频部分使用逐渐尖锐的时间分辨率和较低的频率分辨率，以便移近观察信号的快变部分；在低频部分具有较高的频率分辨率和较低的时间分辨率，以便移远观察信号的慢变部分，小波这种信号分析表示特征对分析非平稳信号是非常有效的，很适合于探测正常信号中夹带的瞬态反常现象并且展示其成分，所以被誉为分析信号的显微镜。
