Aug 29, 2025 · Dirac’s delta function is considered (notation for) a distribution. Specifically it is (and its derivatives are) expressed in terms of the Radon-Nikodym derivative (s) of the …

Feb 12, 2021 · The Dirac delta function, $\delta (t)$, used in continuous time integrals, is different from the Kronecker delta function, $\delta [n]$, used in discrete time summations. Their effect …

Aug 25, 2019 · On Wikipedia, the definition of the dirac delta function is given as: Suppose I have a function where at two points, the function goes to infinity. Given that the distance between …

Mar 15, 2021 · The $\delta$ -"function" is, as others have said, not a function; rather, it's just something which can be integrated, which is not quite the same thing! Making this rigorous …

Oct 11, 2020 · Sometimes considering the delta function is dimensionless is fine but the dimension needs to be fixed by its coefficient, namely the coefficient of the delta function …

The part which I can not understand why the Delta "function" makes sense only when it acts on another function and that too only inside an integral and how is a "functional" or "distribution" …

Aug 25, 2015 · Its unique characteristics do not end there though, because when integrating the Dirac Delta function we would get $$ \int_ {-\infty}^\infty \delta (x) dx = 1$$
