What Does FFT Stand For?

FFT stands for Fast Fourier Transform

FFT, or Fast Fourier Transform, is an efficient algorithm that computes the discrete Fourier transform (DFT) of a sequence, as well as its inverse. By reducing the computational complexity from O(N^2) to O(N log N), FFT enables the rapid analysis of frequency components in signals, making it a crucial tool in various fields such as signal processing, telecommunications, and image analysis. Its application allows for high-performance data processing and real-time analysis of time-series data, contributing significantly to advancements in technology and research.
