Wavelet analysis of vibration signals- data conversion help

Hi

I need help regarding conversion of a dbl 64 bit real value into a waveform dbl. I have used VISA to get data from adxl335 sensor interfaced to an arduino uno and have converted these values in terms of voltage. I want to do wavelet analysis based on multiresolution approach. Is there a way to connect dbl 64 bit real value wire to a waveform dbl wire without using formula waveform. 

My knowlegde in labVIEW is limited. Kindly guide me through this process. 

 

Thanks 🙂

Hi reshma,

Yes, sure!

Build an Y array of your scalar DBL values.

Then use BuildWaveform to create a waveform from your Y data!

Example:

I used a feedback node for easier snippet creation, but you might use shift registers in your loop instead!

 

My knowlegde in labVIEW is limited.

Then you should take the free online resources to learn LabVIEW.

Did you notice the "Getting Started" section right on top of the LabVIEW discussion forum?

Best regards,
