What is another word for FFT?
Pronunciation: [ˌɛfˌɛftˈiː] (IPA) 
FFT is commonly known as Fast Fourier Transform, which is a mathematical algorithm used to transform time-domain data into frequency-domain data. However, there are several synonyms that can be used for FFT. Some of them include spectral analysis, frequency analysis, harmonic analysis, frequency spectrum, frequency domain, and Fourier spectrum. These terms are frequently used in signal processing, audio and video compression and decompression, image processing, and telecommunications. The use of these terms varies depending on the context in which they are used, but they all essentially refer to the same technique of transforming signals from time-domain to frequency-domain. Thus, understanding these synonyms can help enhance communication and professional jargon in different domains.
