Resumen: Fractal interpolation functions provide new methods of approximation of exper­imental data. 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.
