to increase the amplitude of a spectrum

[yogui]

hello,

I have a spectrum and I would like to increase the amplitudes of the fundamental frequency and harmoniques. Is it possible ???

Thank you ?

Hi,

When using "Harmonic distortion analyzer.vi" you can get the fundamental frequency and its multiples in array.

Take the array and perform the scaling you need.

But if you need to increase harmonics for the original signal, this is completely different story which I have no idea how to do it.

The attached VI shows performing an addition to the harmonics detected from a signal.
