Fourier Transforms and the Fast Fourier Transform (FFT) Algorithm
(Occasionally the line between what's signal and what's filter becomes blurry). 1. Page 2. Example of a Fourier Transform. Suppose we want to create

than using direct convolution such as MATLAB's conv command. • Using the DFT via the FFT lets us do a FT (of a finite length signal) to examine signal
A Practical Approach to the Chord Analysis in the Acoustical
The first step of the recognition process is the frequency analysis. For computing the DFT spectrum of the input signal we use the fast Fourier transform (FFT).
