摘要

采用二阶多项式滤波技术对人工稳态视觉诱发电位信号进行平滑处理。以Bhattacharyya distance (BD)作为性能指标，对5、10、15、20、25和30 Hz的基频f(滑动窗L长度恒定)值进行了评价。结果表明，与L相比，较小的f值会降低基频f的峰值。

Second order polynomial filter as filtering technique in steady state visual evoked potential's control signal

Second order polynomial approach has been used as filtering technique to smooth out the artificial steady state visual evoked potential (SSVEP) signal. Bhattacharyya distance (BD) is used as performance metric for evaluating the five different values of fundamental frequency, f, which are 5, 10, 15, 20, 25 and 30 Hz with constant length of sliding window, L. The results indicate that a small value of f compared to L will reduce the peak value of the fundamental frequency, f.
