Dirac delta distribution: Difference between revisions

Revision as of 16:06, 25 May 2007

The Dirac delta distribution (or generalized function) is written as $δ (x)$ . It is the derivative of the Heaviside step distribution,

\frac{d}{d x} [H (x)] = δ (x)

It has the property

\int_{- \infty}^{\infty} f (x) δ (x - a) d x = f (a)
