How to analyze a signal with many samples?

[Rafi2003]

Hi,

I need to analyze (not real time) a signal from a memory containing up to 500,000 samples.  The objective is to plot the time domain, frequency domain and histogram of the data.  In addition, I need to find out some absolute values like p-p, rms, 1'st harmonic level and more...

Can LabView handle such a big chunk of data?

is there an example similar to this objective?

Thanks

Hi Rafi,

"Can LabView handle such a big chunk of data?"

Definitely YES! 500k samples are just 1 or 2MB of RAM - no problem for any modern computer. LabVIEW has FFT and histogram functions (atleast in the betterversions). It has functions for waveform analysis too (atleast you will find toolkits for this purpose).

Or: do it the hard way by programming your own analysis functions

"is there an example similar to this objective?"

There are a lot of examples coming with LabVIEW. Have you looked for them in the example finder?
