What is meant by Fourier transform of real valued function?
In physics and mathematics, the Fourier transform (FT) is a transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency.
The Fourier transform of a continuous-time signal x(t) is given by X ( ? ) = 1 ( 10 + j ? ) 2 , ? ? < ? < ? , where and ? denotes frequency.
