At the same time, Burg is compared with Bartlett of classical spectral estimation, and the choice of position is analyzed. The conclusion is that FPE (Finally Predication Error) is to be used for optimal choice of position.

• 同时比较了Burg算法和经典谱估计中Bartlett周期图法,针对Burg算法中的模型阶次的选择进行了分析,提出了最佳模型阶次采用最终预报误差(FPE)为准则的结论。
