Signal Analysis with DFT(Discrete Fourier Transform) using MATLAB. The first program uses FFT(Fast Fourier Transform) to obtain the DFT of the given audio file to analyze its frequency spectrum, which ...

The Fast Fourier Transform (FFT) is a widely used algorithm that computes the Discrete Fourier Transform (DFT) using much fewer operations than a direct implementation of the DFT. FFTs are of great ...
