What is the Fourier transform of a time shifted function?

Statement – The time shifting property of Fourier transform states that if a signal 𝑥(𝑡) is shifted by 𝑡0 in time domain, then the frequency spectrum is modified by a linear phase shift of slope (−𝜔𝑡0). Therefore, if, x(t)FT↔X(ω) Then, according to the time-shifting property of Fourier transform, x(t−t0)FT↔e−jωt0X(ω)

Does unit step function have Fourier transform?

The unit step function does not converge under the Fourier transform.

What is Fourier transform of unit function?

A Fourier transform (FT) is a mathematical transform that decomposes functions into frequency components, which are represented by the output of the transform as a function of frequency.
