waveform analysis for pulse count and pulse width

[AMGbenz]

Hi all,

I need to have a routine that perform a simple analysis on an input data to determine the pulse width and pulse count of the waveform. I need to analyze this when my array goes above 5 V and down 5 V and that determine one pulse and the pulse width will be from when it goes above 5 to when it goes below 5 and I need to count the number of pulse as the data are coming in.

I need to start off with a while loop and scan through the array.

Could someone give me some info or sample of VI that would do something similiar

LabVIEW version 7 Express

thanks all
