inverse fourier transform imaginary part
Can inverse Fourier transform be complex?
The Fourier transform (and its inverse) is defined as an operator on complex functions of real variable (i.e.
F:CR→CR, f↦F, where f,F:R→C are integrable functions).What is the identity of inverse Fourier transform?
The inverse Fourier transform is exactly the Fourier transform for even functions. γ(x)ψξ(x)dcx = -ξ Jγ(ξ). γ(x)dcx = 1, which is to say that Jγ satisfies the same initial condition as γ as well.
Thus Jγ = γ.What is the imaginary part of a Fourier transform?
If Fourier transform is impedance, then the real part of FT is resistive part of the impedance and imaginary part is the reactive part of the impedance.
