摘要：

A method for isolating and removing very slow activity from EEG records prior to spectrum computation is presented. This is accomplished by an autoregressive filter whose frequency transfer characteristic can be easily controlled. Examples of spectra computed for various filter parameter values are shown. © 1979.
