FFT Unpacked: Demystifying the Fast Fourier Transform

A deep dive into the Fast Fourier Transform (FFT): from the discrete Fourier transform (DFT) to real‑world signals. We'll explore how the divide‑and‑conquer Cooley–Tukey algorithm speeds up Fourier analysis, the inverse transform (IFFT), and why FFTs are everywhere—from audio and image compression to astronomy and wireless communications. We'll also discuss alternative FFT algorithms, practical trade‑offs, and when a direct DFT or other tools might be more appropriate, with intuition and real‑world examples.
