# Dirac Delta Function

- Represented as:

- its value is zero everywhere except at
*x=x*_{0}where its value is infinite. Integrating over any range of*x*that includes*x*_{0}is a unit area. It is, therefore, the limiting case of a pulse with unit area that is infinitely short and at the same time infinitely high.
