Fourier transform

Description

"Fourier transform" calculates the discrete complex Fourier Transform y out of the given signal x according to

with N being the length of the input signal (in samples) using a Fast Fourier Transform (FFT) algorithm.

The type of FFT algorithm used can be set in the Basic Options menu.
