Facts and Fancies About a Posteriori "Wiener" Filtering

  title={Facts and Fancies About a Posteriori "Wiener" Filtering},
  author={Johannes P. C. de Weerd},
  journal={IEEE Transactions on Biomedical Engineering},
A posterior "Wiener" filtering is an estimation technique that has gained renewed interest in recent years, particularly in evoked potential studies. However, several misconceptions appear to exist with respect to the theory and its applicability. The purpose of this paper is to clarify these aspects and to explain the method in a comprehensive manner. Finally, the use of a more powerful time-varying filtering technique is recommended.
