The use of appropriate quantitative tools assigning numerical values to the observed variable is necessary to define good descriptors of the electroencephalogram, allowing comparisons between different recordings. In this line, we propose a numerical method for the spectral and temporal reconstruction of a brain signal. The convergence of the procedure is analyzed, providing results of the concerned approximation error. In a second part of the text, we use the methodology described to the quantification of the bioelectric variations produced in the brain waves for the execution of a test of attention related to military simulation. 000061494 536__ $$9info:eu-repo/grantAgreement/ES/UZ/CUD2013-16 000061494 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000061494 590__ $$a1.017$$b2016 000061494 591__ $$aMATHEMATICS, APPLIED$$b108 / 255 = 0.424$$c2016$$dQ2$$eT2 000061494 592__ $$a0.697$$b2016 000061494 593__ $$aEngineering (miscellaneous)$$c2016$$dQ1 000061494 593__ $$aMathematics (miscellaneous)$$c2016$$dQ2 000061494 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000061494 700__ $$aNavascues, Maria Antonia 000061494 700__ $$0(orcid)0000-0002-8885-7492$$aRuiz, C. 000061494 700__ $$aIso, J.M. 000061494 773__ $$g39, 16 (2016), 4680-4687$$pMath. methods appl. sci.$$tMATHEMATICAL METHODS IN THE APPLIED SCIENCES$$x0170-4214 000061494 8564_ $$s384542$$uhttps://zaguan.unizar.es/record/61494/files/texto_completo.pdf$$yPostprint 000061494 8564_ $$s67026$$uhttps://zaguan.unizar.es/record/61494/files/texto_completo.jpg?subformat=icon$$xicon$$yPostprint 000061494 909CO $$ooai:zaguan.unizar.es:61494$$particulos$$pdriver 000061494 951__ $$a2020-02-21-13:19:05 000061494 980__ $$aARTICLE
