Heaviside step function — The Heaviside step function, H , also called the unit step function, is a discontinuous function whose value is zero for negative argument and one for positive argument.It seldom matters what value is used for H (0), since H is mostly used as a… … Wikipedia
Step function — In mathematics, a function on the real numbers is called a step function (or staircase function) if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant … Wikipedia
Heaviside (disambiguation) — Heaviside usually refers to the mathematician Oliver Heaviside, but it can refer to:* Heaviside step function, named in honor of him. * Heaviside condition, named in honor of him. * Heaviside layer, or Kennelly Heaviside layer, named in honor of… … Wikipedia
Step potential — The Schrödinger equation for a one dimensional step potential is a model system in quantum mechanics and scattering theory. The problem consists of solving the time independent Schrödinger equation for a particle with a step like potential in one … Wikipedia
Step response — The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the… … Wikipedia
Heaviside-Funktion — Die Heaviside Funktion, auch Theta , Treppen , Schwellenwert , Stufen , Sprung oder Einheitssprungfunktion genannt, ist eine in der Mathematik und Physik oft verwendete Funktion. Sie ist nach dem britischen Mathematiker und Physiker Oliver… … Deutsch Wikipedia

Dirac delta function — Schematic representation of the Dirac delta function by a line surmounted by an arrow. The height of the arrow is usually used to specify the value of any multiplicative constant, which will give the area under the function. The other convention… … Wikipedia
Ramp function — The ramp function is an elementary unary real function, easily computable as the mean of its independent variable and its absolute value.This function is applied in engineering (e.g., in the theory of DSP). The name ramp function can be derived… … Wikipedia
Sign function — In mathematics, the sign function is a mathematical function that extracts the sign of a real number. To avoid confusion with the sine function, this function is often called the signum function (after the Latin form of sign ).In mathematical… … Wikipedia
Green's function — In mathematics, Green s function is a type of function used to solve inhomogeneous differential equations subject to boundary conditions. The term is used in physics, specifically in quantum field theory and statistical field theory, to refer to… … Wikipedia
