Fft used for

The FFT is used to process data throughout today's highly networked, digital world. It allows computers to efficiently calculate the different frequency components in time-varying signals—and also to reconstruct such signals from a set of frequency components.

Where is FFT algorithm used?

The FFT algorithm is heavily used in many DSP applications. It is used whenever the signal needs to be processed in the spectral or frequency domain. Because it is so efficient to implement, sometimes even FIR filtering functions are performed using an FFT.

Where is fast Fourier transform used?

Applications. The FFT is used in digital recording, sampling, additive synthesis and pitch correction software. The FFT's importance derives from the fact that it has made working in the frequency domain equally computationally feasible as working in the temporal or spatial domain.

What is the main advantage of FFT?

The main advantage of an FFT is speed, which it gets by decreasing the number of calculations needed to analyze a waveform.

Why FFT is used in communication?

At the receiver, an FFT is used to recreate the multiple subchannels, with long duration symbols. (The FFT recreates a frequency domain signal, with its multiple subcarriers, from the time domain signal received over the air.) In stereo FM, much the same is happening.
