The Fourier Transform
Fast Fourier Transform for Signal Analysis
Description
The Fast Fourier Transform (FFT) is a computational algorithm that makes the Discrete Fourier Transform (DFT) faster to calculate. It works by splitting the calculation into smaller parts. This reduces the amount of work needed to move data between the time domain and the frequency domain.

Transcript
The Fast Fourier Transform, FFT, is a computational algorithm for calculating the Discrete Fourier Transform by breaking the calculations into smaller, manageable sections.
Computing an N-point DFT requires N square complex multiplications, while the FFT algorithm requires only N over two and base two logarithm N multipli...
