Fast Fourier Transform (FFT)

Open table with initial data and use Analysis -> Fast Fourier Transform menu item to perform FFT.

Formulas

MagicPlot uses 'electrical engineering' convention to set the sign of the exponential phase factor of FFT. 1) Most scientific applications uses the same sign conventions. But note, that the sign of exponential phase factor in Numerical Receipts in C, 2nd edition, p. 503 is the opposite

Here is signal components and spectrum components, n = 1...N.
