Understanding the FFT Algorithm
Read OriginalThis technical article dives into the Cooley-Tukey Fast Fourier Transform (FFT) algorithm, explaining the computational symmetries that make it efficient. It contrasts the naive O[N^2] Discrete Fourier Transform with the FFT's O[N log N] approach, provides the mathematical definitions, and demonstrates how to implement the FFT from scratch in Python, moving beyond standard library wrappers like NumPy and SciPy.
