HOW DO I GENERATE ANALOG SIGNAL FROM A FILE BY LABVIEW / NI CARD

[bharath_reddy]

Hi every one. I'm really new in Labview and maybe my question is trivial for some users but I'm still having a hard time trying to figuring out how to get this done in Labview.

This is my situation:

I got a huge text file with 650000 samples that belong to a non-periodic signal. We need to read from this file and generate an analog output by reading its values (file is a TEXT format&MAT format) and then recreate the signal by doing periodic D/A conversions (this is not an issue). This analog signal is going to serve as signal generator for the analysis of one implementation of one real time algorithm.  At the same time, we are going to take the waveform to give input to our algorithm.

Any ideas on how to accomplish this on Labview / NI card of DAQ?

Best Regards,

Read the whole file via the "Read from Text File.vi", put it into an array, then feed the array into your driver for output generation...

The question is far to vague, and borders on a "teach me labVIEW" question, which we can't exactly do over a message board.
