In this context, the Heaviside function is the cumulative distribution function of a random variable which is almost surely 0. (See constant random variable .) In operational calculus, useful answers seldom depend on which value is used for H (0) , since H is mostly used as a distribution . See more The Heaviside step function, or the unit step function, usually denoted by H or θ (but sometimes u, 1 or 𝟙), is a step function, named after Oliver Heaviside (1850–1925), the value of which is zero for negative arguments and See more Often an integral representation of the Heaviside step function is useful: where the second representation is easy to deduce from the … See more An alternative form of the unit step, defined instead as a function H : ℤ → ℝ (that is, taking in a discrete variable n), is: or using the half … See more The ramp function is an antiderivative of the Heaviside step function: The distributional derivative of the Heaviside step function is the Dirac delta function See more For a smooth approximation to the step function, one can use the logistic function where a larger k corresponds to a sharper transition at x = 0. If we take H(0) = 1/2, equality holds in the … See more Since H is usually used in integration, and the value of a function at a single point does not affect its integral, it rarely matters what particular value is chosen of H(0). Indeed when H is considered as a distribution or an element of L (see L space) it does not even … See more The Fourier transform of the Heaviside step function is a distribution.
