A temporal-spatial filter is designed for noise removing of clinical EEG signals, the first filtering is temporal filtering using band-pass filter, and the second filtering is spatial filtering with ICA-based spatial filter.

• 为了有效去除临床脑电信号的噪声和干扰，设计了一种时空滤波器，分两个阶段对脑电信号进行滤波预处理：第一个阶段是时域滤波，用传统的带通滤波器实现；第二个阶段是空域滤波，用基于独立分量分析(ICA)的空域滤波器实现。
