Dirac delta distribution: Difference between revisions

Revision as of 16:38, 21 March 2007

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

{\frac {d}{dx}}[H(x)]=\delta (x)

It has the property

\int _{-\infty }^{\infty }f(x)\delta (x-a)dx=f(a)
