The 18 pages that link to Dirac delta function, each with the reason it gives.

• Green's functionRelated: A Green's function is defined as the operator's response to this idealized source.

• Fourier analysisRelated: It describes idealized impulses and clarifies the transform of localized inputs.

• ConvolutionRelated: Convolving with it leaves a function unchanged.

• Impulse responseRelated: It models the input whose resulting output defines an impulse response.

• Heaviside step functionRelated: The step’s distributional derivative is a Dirac delta at its jump.

• Oliver HeavisideRelated: Impulse inputs connect Heaviside’s step-function methods with later distribution theory.

• Point (geometry)Related: It models point-concentrated quantities without being a geometric point.

• Point chargeRelated: It expresses a point charge's spatial charge density mathematically.

• Fermi's golden ruleRelated: The energy delta function enforces conservation between initial and final energies.

• Sign functionRelated: In distribution theory, the derivative of the sign function is twice a delta at zero.

• SourceRelated: An ideal point source is represented by concentrated divergence at its location.

• Wiener–Khinchin theoremRelated: Ideal white noise has a delta-shaped autocorrelation and a flat spectrum.
