Zero filling

Post by Lautibah »


I have been told that I should use the "zero filling" option before using Fourier transformations, to get smoother data. Nevertheless I have not seen the option in magic plot.

Is it hidden somewhere?

Thank you.

Yes, you are right, the zero filling of the signal before Fourier transform can increase the resolution of the spectrum. But this feature is not implemented in MagicPlot yet, as the windows functions for FFT. You can fill your column with zeroes in the data table using formula dialog.
