    The "Dirac delta function" is more commonly called just "the delta function". It is not, in fact, a "function" but rather a "generalized function" or "distribution". Roughly speaking that's a that's a functional: an operator that assigns a number to every function. The delta function assigns the number f(0) to every function f (so [itex]\delta(t- a)[/itex] that Defennnder show assigns the number f(a) to every function f).
