What is a Discrete Fourier Transform (DFT) and an FFT?
на канале: Iain Explains Signals, Systems, and Digital Comms
Explains how the output of a DFT, and a Fast Fourier Transform (FFT), relates to the Fourier Transform of real-time signals. As pointed out in the video, note that the FFT gives the same output as the DFT - it's just a more efficient implementation of the function.
