How to seperate the pulses that are acquired from real world according to their pulse heights in LabVIEW.

[GiridharYadav]

Hi everybody,

Can any one help in getting out this. Actually I am acquiring gamma rays from proportional counter into the LabVIEW, Coming to the analysis part, I need to seperate the pulses according to their pulse heights. After seperating them I need to digitise the pulses that are seperated. So I request you to sort out this as early as possilbe.

Thanks in advance.

I am confused about your description. You indicate that you are acquiring the signals but then you want to digitize them later? Any signal processed by LabVIEW has already been digitized because the software only works on numbers, not continuous voltages.

1. How are you acquiring the data from the proportional counter into LV? What DAQ device are you using? What sample rate?

2. What is the duration of the pulses? Gamma pulses from PMT and scintillators are usually rather short.

3. Do you have any log amplifiers or other signal conditioning between the detectors and the DAQ device?
