What Fourier transform be called? Correlation or convolution?

  1. Jun 14, 2015 #1
    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.
