[Study of the functional structure of the EEG by means of the ambispectrum and ambicoherence (author's transl)].
An extension of spectral analysis by calculation of the ambispectrum and ambicoherence is defined, tested on pulsed and random signals, and then applied to the study of the functional structure of the electro-encephalogram. Preliminary results are similar to those obtained by the use of the biospectrum and bicoherence, and also allows comparison between frequency components of signals from different topographical origin.
