Abstract：In order to achieve the integration of EEG signal processing and analysis,as well as extracting effective characteristic EEG indicators for improving the EEG reading speed,a virtual electroencephalogram (EEG,)signal analyzer was designed by Lab-VIEW.The platform could simulate the routine EEG display interfaces.First ,the open biomedical Toolkit and MATLAB script were a-dopted for filtering.Next,the EEG power spectrum was calculated based on the frequency domain analysis,and further extraction of four EEG components(δ,θ,α,β)were analyzed.The results showed that wavelet de-noising had better retention of EEG informa-tion than Fourier filtering did,in addition,the use of MATLAB node could enhance scalability.The differences of four rhythms be-tween interictal and ictal seizures were studied and the change degree varied significantly with different rhythms.
