Understanding the Discrete Fourier Transform and the FFT

Understanding the Discrete Fourier Transform and the FFT

The discrete Fourier transform (DFT) transforms discrete time-domain signals into the frequency domain. The most efficient way to compute the DFT is using a fast Fourier transform (FFT) algorithm. This Tech Talk answers a few common questions that are often asked about the DFT and the FFT. It covers an overview of the algorithm where you’ll ...
