How to extract Harmonics as sinusoid waves

[Gurdas]

Hi!

We have a wave from which we would like to extract harmonics 1 to 12 and display the harmonics as sinusoid.

Presently we use "Auto Power Spectrum.vi" and then feed its o/p to "Harmonic Analyzer.vi".
What we get is single o/p showing amplitudes and frequencies of each harmonic.

How do we get the same as sine wave showing phase relationship?

Thanks,
Gurdas

Hi,

you are right, the Harmonic Analyser doesn't give you phase information.
What you could do is calculate the "Amplitude and Phase Spectrum" and look for the frequencies your Harmonic Analyser has found. There you can get the phase.
To display the harmonics in time domain I would suggest building your own waveforms with "Sine Waveform" (in a loop for all detected frequencies).

Tell me if you need more information.
