Table of Contents
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)
Here is signal components and
spectrum components, n = 1…N.
| Normalize Check Box | Forward Transform | Inverse Transform |
|---|---|---|
| Unchecked | | |
| Checked | | |
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
