Question

If the Fourier transform of f(x) is F(s), then f(x) is equal to

Answer 1

Answer:

I have also U So a answer in sum to me and my family.

Answer 2

If the Fourier transform of f(x) is F(s), then f(x) is called self-reciprocal

Self-reciprocal

If the Fourier transform of f (x) is obtained just by replacing x with s, then f(x) is called self-reciprocal concerning Fourier transform.

In the question, it is mentioned that the Fourier transform of f(x) is F(s). Hence, it is termed self-reciprocal and its Fourier transform will be obtained by just replacing x with s.
