Abstract :
The distortion effects upon the measurement of EEG spectra are investigated. A non-linear model of zero-memory type is used for the input-output relation of the measurement system. The model is identified by means of measured second and third harmonics. Examples illustrate the distortion effects upon power spectra of waking infant and adult EEG´s.
