Count pulses in digital waveform

[Pavolo]

Hello everybody,

I need to count the pulses of a digital waveform. I have looked at the examples related to this, but all of them seem to use a signal acquired by a digital counter input. I already have the signal in my computer, so using a device input makes no sense. And I searched the function library but found nothing. Which LabView functions should I use?

Thank you in advance for your time and help,

SOmething like this should work for a simple digital wave.

Thank you for your answer.

It seems to be a Labview 9.0 file and I have Labview 8.2. Could you save it in compatibility mode or at least upload a screenshot?

Here you go. 8.2

Hello friend,

Here, i have attached VI... In this VI i need to count the number of cycle in the pulse and also find the pulse count without give the threshold value to the signal(analog & digital).

If you got a solution, that code can  be implemented for all the waveform signals..

could you please help me...
