Web68 LECTURE 16. LIMITATIONS OF THE FOURIER TRANSFORM: STFT 16.3 The Short-Time Fourier Transform In the STFT, we perform a series of windowing and FT operations: at each time shift t, A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow to be practical…
