Sifting Property -- from Wolfram MathWorld

WebThe sifting property of the discrete time impulse function tells us that the input signal to a system can be represented as a sum of scaled and shifted unit impulses. Thus, by linearity, it would seem reasonable to compute of the output signal as the sum of scaled and shifted unit impulse responses. WebThat unit ramp function \(u_1(t)\) is the integral of the step function. The Dirac delta function \(\delta(t)\) is the derivative of the unit step function.
