What Fourier transform be called? Correlation or convolution?

Click For Summary
SUMMARY

The discussion clarifies the relationship between Fourier transforms, convolution, and correlation. Specifically, it establishes that the Fourier transform is neither purely a correlation nor a convolution but has a distinct mathematical identity. The key takeaway is that the Fourier transform of a product of two functions results in the convolution of their individual transforms, highlighting the interconnectedness of these concepts in signal processing.

We know that in the Fourier transform formula ,there are mainly two terms function f(t) and complex exponential term ( function).


But I am confused that what should i call Fourier transform formula as a correlation or convolution formula? So can anybody help regarding it?

You need to describe what you are looking for. Fourier transform, convolution, and correlation are all different concepts.

There is a connection between the Fourier transforms and convolutions - the Fourier transform of a product of two functions is the convolution of the individual transforms, and vice versa.
