Analysis of epileptic signals based on discrete Hartley transform and discrete Fourier transform

Abstract

In this paper, the proposed approach to the problems of assessing the rhythms of the brain develops an analysis is made of the existing features of processing neurological signals. For the analysis of epileptic discharges, which are the focus of work, it is proposed to use orthogonal transformations. This was done on the basis of a reasoned model of epileptic discharges as a class of broadband pulse signals. The analysis of the main features of the discrete Fourier and Hartley transforms is presented as the main methods of signal processing in the case of epileptic seizures is carried out. The results of the analysis of the real, containing a fragment of the epileptic discharge of the EEG record obtained on the basis of the proposed approach are presented.
