Harmonics analysis

QuickField provides built-in Harmonic analysis utility. However, it works with space-distributed values only. Sometimes it is required to find the harmonics of other dependencies. Here you can find the script that can perform harmonic analysis for input data of any nature. You can copy data from QuickField time-tables or LabelMover results and automatically calculate the magnitude and phase of any harmonic specified by its number.

Number of harmonics to calculate: Run Fourier analysis

Approximation: $$f\mathrm{(}t\mathrm{)}=\mathrm{A0}+\sum _{\mathrm{k}}^{\mathrm{}}{A}_{\mathrm{k}}*\sin (\frac{\mathrm{2\pi }·k·t}{T}+{\mathrm{phase}}_{\mathrm{k}})$$
period T=,
average A0 = .

Total harmonic distortion =

Mean squared error =
