Spectral edge frequency (e.g. SEF95)

Frequency below which pct fraction of total power lies. SEF95 (pct = 0.95) is a classical EEG depth-of-anaesthesia marker.

Usage

morie_dsp_spectral_edge(psd, freqs, pct = 0.95)

Arguments

psd

PSD vector.

freqs

Matching frequency vector.

pct

Cumulative fraction in (0, 1]. Default 0.95.

Value

Scalar (Hz).
