Amp_Spectrum_GUI

single-sided amplitude spectrum GUI

Get single-sided amplitude spectrum, matlab script based, no fig file (not guide or app designer), easy to use. No toolbox required.

1. select variable from workspace, if data is 2 row or 2 column, 1st row or column will be time. gui will auto fill "scale" box (sampling frequency)
2. zoom in the range of interesting, spectrum only from these data
3. input scale, if input sampling frequency fs, the unit of x axis is hz. if input fs/ref_freq, x axis will be ref to ref_freq. for example, 1x,2x... motor frequency
4. Set spectrum resolution
5. select window function
6. if you want to check what is 2x motor frequency in time domain, input 2 in grid box, it will draw grid.
7. export result data in workspace
