Spectrum analyzer - Wikipedia
https://en.wikipedia.org/wiki/Spectrum_analyzer
An FFT analyzer computes a time-sequence of periodograms. FFT refers to a particular mathematical algorithm used in the process. This is commonly used in conjunction with a receiver and analog-to-digital converter. As above, the receiver reduces the center-frequency of a portion of the input signal spectrum, but the portion is not swept.
Fast Fourier Transformation FFT - Basics - NTi Audio
https://www.nti-audio.com/en/support/know-how/fast-fourier-transform-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. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems.

The FFT (Fast Fourier Transform) was developed in 1965 (Cooley+Tukey). were repeated. By a means of algorithms FFT tries to reduce these repetitions thereby increasing calculation efficiency, particularly as the number of samples increases. Calculation is said to be more efficient where it is carried out on a block of samples where the block
