Does Fourier transform remove noise?

Examples of such applications are canceling out electromagnetic conditions in radar measurements [5], echo suppression in audio processing [6], and 2D noise filter in image processing [7]. In the above, Fourier transform has proven to be functional and efficient tool for noise reduction.

What is FFT phase spectrum?

The FFT function computes the complex DFT and the hence the results in a sequence of complex numbers of form . The amplitude spectrum is obtained. For obtaining a double-sided plot, the ordered frequency axis (result of fftshift) is computed based on the sampling frequency and the amplitude spectrum is plotted.

What is FFT in noise?

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal.
