The Fourier (Blog) Series Part 1 – Introducing The DFT

The FFT is one of the backbones of signal processing, allowing us to quickly transform a signal from time-domain to frequency-domain (and vice-versa via the inverse FFT). This allows us to analyze or manipulate the signal such as filtering, noise reduction, pitch detection or correction, time-stretching or even removing elements from the signal. The FFT
