In the continuum, the unit jump function Msx was computed as being the subtraction between Hevisides function Hsx and an arbitrary continuous function φx. limited by a small band Ω in S , as indicated in Figure 4
La función elemental de salto unitario en el continuo Msxse calcula como la diferencia entre la función de Heaviside Hsxy la función continua jxdefinida en una pequeña banda Wcontenida en Scomo se indica en la Figura 4.
