Spectral edge frequency : ウィキペディア英語版 | Spectral edge frequency The spectral edge frequency or SEF is a measure used in signal processing. It is usually expressed as "SEF ''x''", which stands for the frequency below which ''x'' percent of the total power of a given signal are located. (typically ''x'' is in the range 75 to 95.) It is more particularly a popular measure used in EEG monitoring, in which case SEF has variously been used to estimate the depth of anesthesia. ==See also==
