How do you do FFT?
The FFT operates by decomposing an N point time domain signal into N time domain signals each composed of a single point. The second step is to calculate the N frequency spectra corresponding to these N time domain signals. Lastly, the N spectra are synthesized into a single frequency spectrum. separate stages.
What is FFT algorithm used for?
The FFT algorithm is one of the heavily used in many DSP applications. It is used whenever the signal needs to be processed in the spectral, or frequency domain. It is so efficient to implement, that sometimes even FIR filtering functions are performed using an FFT.
How do you explain FFT?
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.
