FFT-Filter provides a GUI to remove periodic baselines from measurements by FFT-filtering the data.
Project description
FFT-Filter
This package provides an interactive GUI to remove periodic baselines from measurements. The software can be started by running
fftfilter
in the terminal.
Files can be loaded via drag-and-drop or via the menu.
The data is Fourier tranformed and all Fourier coefficients below a user-selected cutoff are removed before the reverse Fourier transform is performed.
The files are expected to be tab-separated and the first two columns are expected to be the x- and y-data of the measurement.
This procedure is quite effective for removing standing waves (e.g., due to reflections, ...) from measurements.
