What is the Fourier transform of a real valued signal?
The Fourier Transform of real valued signal is always of conjugate symmetry.
Is Fourier transform of a real signal real?
Theorem 5.3 The Fourier transform of a real even function is real. Theorem 5.4 The Fourier transform of a real odd function is imaginary. f(t)sin(2?st)dt which is imaginary.
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.
