Labview algorithm for voltage threshold pulse counting

[AlphaBetaGamma]

I have NI PCI 6024E daq card and im using labview  2010 with daqmx.

I have a signal which contains pulses that i have to count. The problem is that in addition  to the pulses there are some small voltage spikes as well in the signal. When i try to count the rising  edges using counter, it counts the small voltage unwanted spikes as well and therefore gives a false reading. 

I tried to find a way so that a threshold could be set for the counter so that counter counts only the pulses that cross that threshold but i came to know that counters doesnt have such threshold  feature. 

I need suggestions about how can i approach this issue? 

Preferably  i would like to implement  a software solution to this problem. 

Thanks alot

Not a software fix: How about a simple RC filter ?    

(dedicated counters sometimes have a analog threshold setting... , but that doesn't help here unless you build a comparator with settable  threshold)

and isn't there a debounce filter for the counters, that maybe work?  Depending on the actual pulse and spike timings  you didn't 'valued' 😉

A software solution would be the median filter as a preprocessing for the analog  pulse counter, that will remove spikes and 'sharpen' the edges.
