This chapter begins with the actual computation of frequency spectra for discrete time systems. For brevity, we will use the acronyms DFT for the Discrete Fourier Transform and FFT for Fast Fourier ...

There are many books and articles on the Fourier Transform and its implementation available. A quick survey of these resources shows that they are not geared to the needs of the “Practicing ...

A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...
