fourier transform of heaviside step function
The Fourier transform of the Heaviside function: a tragedy
28 sept 2005 · This function is the unit step or Heaviside1 function A basic fact about H(t) is that it is an antiderivative of the Dirac delta function:2 |
As illustrated in Fig. 2.15, the derivative of the Heaviside function is the Dirac delta function, which is usually denoted as the δ-function.
It values zero everywhere except at the origin point t = 0.
What is the Fourier series expansion of the Heaviside function?
Thus, the Fourier-Legendre series expansion for the Heaviside function is given by f(x)∼12−12∞∑n=1(−1)n(2n−3) (2n−2) 4n−12nP2n−1(x).
What is the Heaviside step function?
The Heaviside step function H(x), also called the unit step function, is a discontinuous function, whose value is zero for negative arguments x < 0 and one for positive arguments x > 0, as illustrated in Fig. 2.2.
