What are FFTs?

Career: Fft

FFTs, or Fast Fourier Transforms, are algorithms used to compute the Discrete Fourier Transform (DFT) and its inverse efficiently. They are essential in signal processing, audio analysis, image processing, and many other scientific and engineering applications. FFTs help convert signals from the time domain to the frequency domain, making it easier to analyze the frequency components of a signal. The most popular FFT algorithm is the Cooley-Tukey algorithm, which significantly reduces the computational complexity compared to direct computation of the DFT.
