DFT Definition and Properties
(Complete Item Description)
- Abstract:
The discrete Fourier transform (DFT) and its inverse (IDFT) are the Primary numerical transforms relating time and frequency in digital signal processing. The DFT has a number of important properties relating time and frequency, including shift, circular convolution, multiplication, time-reversal and conjugation properties, as well as Parseval's theorem equating time and frequency energy.
