In the present paper, a fractal technique generalizing cubic spline functions is applied. Under sorne hypothesis about the original signa!, error bounds of interpolation are given. Additionally, a quadrature formula to calcule the Hjorth mobility of a electroencephalographic recording is proposed, that complements the description of the signa! in the frequency domain. The results about the conver­gence of interpolation functions allow to deduce an expression for the computation error of the quantifying parameter by the method described.2001http://zaguan.unizar.es/record/150434http://zaguan.unizar.es/record/150434oai:zaguan.unizar.es:150434Revista de la Academia de Ciencias Exactas, Físico-Químicas y Naturales de Zaragoza 56 (2001), 77-92All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
