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 one for positive arguments. It is an example of the general class of step functions, all of which … 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 limit: There are See more Often an integral representation of the Heaviside step function is useful: where the second representation is easy to deduce from the first, given that the step function is real … 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 Fourier transform of the Heaviside step function is a distribution. Using one choice of constants for the definition of the Fourier transform we have Here p.v.1/s is 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 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 The Laplace transform of the Heaviside step function is a meromorphic function.
