提出了一种去除工频噪声及谐波成分的方法,克服了噪声频率漂移时窄带滤波器所存在的困难,避免了滤波过程引起的附加失真,有效地抑制了混叠在诱发脑电信号中的工频噪声
A method to eliminate common-frequency noise and harmonic components is proposed, which overcomes the difficulties existing in the narrow-band filter during noise frequency drift, avoids the additional distortion caused by the filtering process and effectively suppresses aliasing in induced EEG signals The frequency noise
