Derivative of the ramp function
The ramp function satisfies the differential equation: where δ(x) is the Dirac delta. This means that R(x) is a Green's function for the second derivative operator. Thus, any function, f(x), with an integrable second derivative, f″ (x), will satisfy the equation: Fourier transform [ edit] See more The ramp function is a unary real function, whose graph is shaped like a ramp. It can be expressed by numerous definitions, for example "0 for negative inputs, output equals input for non-negative inputs". The term "ramp" can … See more The ramp function has numerous applications in engineering, such as in the theory of digital signal processing. In finance, the payoff of a call option is a ramp (shifted by strike price). Horizontally flipping a ramp yields a put option, while vertically flipping … See more • Tobit model See more The ramp function (R(x) : R → R0 ) may be defined analytically in several ways. Possible definitions are: • A See more Iteration invariance Every iterated function of the ramp mapping is itself, as See more Webdifferentiating ramp function gives step function. differentiating step function gives impulse function. so 2nd derivative of ramp function is impulse function. 5 Gordon M. …
