increase or decrease the number of points in a waveform without affecting the waveform shape

[Amruth]

Hi,

I have captured 1000 samples of a arbitrary waveform using analog measurement card, all the 1000 samples represent a complete cycle of the waveform.

Now I want to increase the Number of samples to 1200, so that all 1200 samples represent the same complete cycle, without effecting the waveform rate.

And I want to reduce the Number of samples from 1000 to 750, so that all 750 samples represent the same complete cycle.

Is this possible? any mathematical solution is there for my requirement? if any one have solution for my qsn please help me.

Thank you.

Hi,

maybe see here.

I had to do the same thing in my project.

The first solution I've thought about is a mahematical interpolation.
It gives me good results for my application. I used the Advanced Analysis Library from CVI.

Hope it will help.
