The Discrete Fourier Transform
Fourier analysis is a family of mathematical techniques, all based on decomposing signals into
sinusoids. The discrete Fourier transform (DFT) is the family member used with digitized
signals. This is the first of

Lecture 7 - The Discrete Fourier
Transform
7.1 The DFT
The Discrete Fourier Transform (DFT) is the equivalent of the continuous Fourier
Transform for signals known only at instants separated by sample times (i.e.
a finite sequence of data).
Let be the con
