What is signal decomposition?

Abstract. The goal of signal decomposition is extraction and separation of signal components from composite signals, which should preferably be related to semantic units. Examples for this are distinct objects in images or video, video shots, melody sequences in music, spoken words or sentences in speech signals.

What does FFT do in Python?

The fast Fourier transform (FFT) is an algorithm for computing the discrete Fourier transform (DFT), whereas the DFT is the transform itself. Another distinction that you'll see made in the scipy. fft library is between different types of input. fft() accepts complex-valued input, and rfft() accepts real-valued input.
