WebFourier Transform of the Unit Step Function How do we know the derivative of the unit step function? The unit step function does not converge under the Fourier transform. But just as we use the delta function to accommodate periodic signals, we can handle the unit step function with some sleight-of-hand. WebApr 11, 2024 · The function works for all the levels except for the case of t =0. Hence the derivative of the step function becomes zero for all values of t. However, it becomes infinite when t = 0. In the unit step function, its derivative is known as an impulse function. Engineers use impulse functions to draw a model for certain events.
