Fourier Transform (FT) and Inverse
The Fourier transform of a signal
,
, is defined as
![$\displaystyle X(\omega) \isdef \int_{-\infty}^\infty x(t) e^{-j\omega t} dt, \protect$](img1682.png) |
(B.1) |
and its inverse is given by
![$\displaystyle x(t) = \frac{1}{2\pi}\int_{-\infty}^\infty X(\omega) e^{j\omega t} d\omega. \protect$](img1683.png) |
