AKA digital signal processing (DSP). A signal is an information-carrying wave, but in the digital sense, a 'signal' refers to either received or transmitted streams/blocks of data, commonly representing real-world quantities such as audio levels, luminosity, pressure etc over time or distance. 'Processing' is the act of altering, analyzing or characterizing the data to retrieve/modify information inherent in the signal in question.

DFT (Discrete Fourier Transform) Algorithm in Swift
This is not a language specific problem.
The Discrete FT running time is theta(N^2), and as you note, it is not fast. However the Fast FT is named as such because it has theta(N lg N) performance. J …
