Open table with initial data and use
Analysis → Fast Fourier Transform menu item to perform FFT.
MagicPlot uses 'electrical engineering' convention to set the sign of the exponential phase factor of FFT. 1)
Here is signal components and spectrum components, .
| Normalize |
| Forward Transform |
| Inverse Transform
|Sampling Interval|| Sampling interval is used to compute the data in resulting sampling column which will be
| Real |
| Columns with real and imaginary components of data.
If your data is only real, select
| Forward |
|Normalize forward transform|| Divide forward transform result by number of points N
|Center zero frequency||If selected, after forward Fourier transform the two parts of spectrum will be rearranged so that the lower frequency components are in the center; the opposite rearrangement of spectrum will be done before inverse transform if any.|
