MagicPlot uses 'electrical engineering' convention to set the sign of the exponential phase factor of FFT as follows from the table below. 1)
| Normalize Forward |
| Forward Transform |
| Inverse Transform
Here are complex signal components and are complex spectrum components, .
| Center Zero |
|Sampling Column Values|
Here is given sampling interval of initial data.
|Sampling Interval|| Sampling interval is used to compute the data in resulting sampling column. If
| 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.|
