Filter banks analysis is an easy and quick computing way to implement time-scale methods, these being well suited for short events as well as for large waveforms detection tasks. We propose a non-uniform oversampled filter banks to analyze sleep EEG single channel signal, the different subbands matching the classical EEG rhythms. In order to preserve the temporal shapes information, filter banks are oversampled. Coupling the informations conveyed by the different outputs allow to perform an automatic hypnogram.
滤波器组分析是一种实现时标方法的简单快速的计算方式，这些方法非常适合于短事件以及大波形检测任务。我们提出一种非均匀过采样滤波器组来分析睡眠脑电图单通道信号，不同子带匹配经典脑电节律。为了保留时间形状信息，滤波器组进行了过采样。将不同输出所传达的信息耦合起来可实现自动睡眠图。
