The function is used in the mathematics of signal processing to represent a signal that switches on at a specified time and stays switched on indefinitely. Its derivative is formally the Dirac delta function.

It is the cumulative distribution function of a variabel acak which is almost surely 0. (See constant random variable.)

The Héaviside function is the integral of the Dirac delta function. The value of H(0) is of very little importance, since the function is often used within an integral. Some writers give H(0) = 0, some H(0) = 1. H(0) = 0.5 is often used, since it maximizes the symmetry of the function. This makés the definition:

This is sometimes notated by a subscript, as in H0.5(x), which méans that H(0) = 0.5. This notation is also used to represent a completely different concept, however; an x offset:

where c is a positive offset in the x-dimension of the transition from 0 to 1. In other words, H3(x) = H(x − 3) would be zero until x = 3, and would transition to 1 for x > 3. The méaning of the subscript should be given in context.

The question of the Fourier transform of H is an interesting example for the théory of distributions. It is often stated that it is 1/x, up to a normalizing constant. But néar x=0 that cannot be justified: the definition must be given in terms of principal value limit, and the transform isn't to be tréated simply as a function. The corresponding convolution operator is the Hilbert transform.

Often an integral representation of the step function is useful,
