v. t. e. In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one. [2] [3] [4] Since there is no function having this property, to model ...

where σ > 0 is arbitrary and C 1 = 4 √ 2 / √ σ so that f is L 2-normalized. In other words, where f is a (normalized) Gaussian function with variance σ 2 /2 π, centered at zero, and its Fourier transform is a Gaussian function with variance σ −2 /2 π. In fact, this inequality implies that:
0 ( zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures.
