Web• Delta Function 𝛿(𝑡) [Defination: A inverse fourier transform of a constant function of 1] - The Delta function are infinite at 0, and are 0 at else place. Therefore the area under delta function's curve always 1. - The Integration of a 𝛿(𝑡) is a Unit Step Function [also called Heaviside Step Function u(t)] The Fourier transform of the Heaviside step function is a distribution. Using one choice of constants for the definition of the Fourier transform we have Here p.v.1/s is the distribution that takes a test function φ to the Cauchy principal value of . The limit appearing in the integral is also taken in the sense of (tempered) distributions. ezpawn north las vegas nv
