feature extraction

HI I am looking for the labview code for the feature extraction of a signal through FFT and wavelet. Features like kurtosis, root mean square (RMS), Peak-to-peak value variance, crest factor and skewness Anyone have some helping code Or tutorial please share it, or send me on my email address:

 

adamfamily1978@yahoo.com

 

Another question is that the labview can do the classification of extracted features through neural network?

 

Thanks.

 

Regards,

Adam

Hi Adam,

 

I think that most of the analysis functions you're looking for live in the Mathematics » Statistics and Probability Palette.  Kurtosis, skewness, and RMS finding functions exist on that palette, and I believe you'll be able to build a simple algorithm to calculate Peak-to-Peak variance.

 

Could you also clarify your question about neural networks?

 

Regards,
