Analysis device of the signals for the detection of potentials cerebral

摘要

Of the circuits 14, 16 receive electrical signals collected by means of a sensor 10 in response to stimulation. The digitized signals are received by a calculating device 20 for generating a signal representing, in the time domain, the average of a certain number of response signals collected; the fourier transform of the averaged signal; in order to detect sinusodes exponentially damped contained in the fourier transform of the averaged signal and determining the parameters of the sinusodes detected, in order to deduce the parameters of the data characterizing the waves of the evoked potential contained in the averaged signal.
