Joseph Fourier first represented Fourier integral theorem in the following DOE: DOE1.jpg[1] Which is then introduced into the first delta function as following: DOE2.jpg[1] And the end end up with what mathematicians called Dirac delta function: DOE3.jpg [1] The input x(t) is a function with a fundamental period x(t)= 1 from x= 0 to 1 and f(x)= -1 to 0, with a discontinuity at x=0. The following graphs from matlab represents Gibbs phenomena, as n increases the overshot decreases.
