| 摘 要： | 应用快速傅里叶转换技术对正常视网膜电图进行频域分析，发现其ａ、ｂ波的优势频及能量集中在５－７５Ｈｚ；与ＯＰＳ波的分离点为７７ＨＺ，从而提出单纯记录ａ、ｂ波及ＯＰＳ波各自的较理想的通频带。

| Abstract: | The Fast Fourier Transform of ERG in normal subjects was investigated.Fourier
spectrum and powerdistribution of frequency-domain were analyzed.The frequency-domain and
power of a,b wave were in 5-75Hz ; the separated point of a,b wave and OPs wave was in 77 Hz,A
reasonable method was developed bythe authors to evaluate the frequency band of a ,b wave and
OPs wave independently. |
