how to detect pulse!!!

[bhotu]

Hi!

I have attached pulses.jpeg files here. I have captured pulses through ai0. But I want to detect these pulses. How to detect pulses without using counter.  I want to make program like if pulses detect than LED becomes ON and if there is no pulses than it leaves off.

Thanks

I'm assuming the downward spikes are your pulses? There are several VIs available in LabVIEW that can be used to do this: Peak Detector, Pulse Measurements, Transition Measurements. Just open up the LabVIEW Help and read up on them.

hi!

I don't want to measure and detect peaks. But I want to just detect pulses for 5 seconds . if it stays then LED gonna turn ON. If not than LED leaves off.

I do believe I mentioned 2 other functions besides Peak Detect. Did you look at these other functions? You showed a picture, but did not explain it. What is the pulse? Does the picture show one pulse, or 4 pulses?

Are you gathering a chunk of data (more than 5 seconds) and want to see that there was a pulse during that 5 seconds?

Please provide more details and a more precise answer can be provided.

hi! thanks for your prompt reply.

I don't want to do anything with data. Just I want to detect pulses. I want to check that pulses are generated continuously for 5 seconds. I have captured pulses as i have sent .jpg files. but i couldn't  figured out that how to detect pulses. Basically I wanna check pulse generator works or not. I don't care about pulse data.

I'm sorry, but I really don't understand what you're asking. Are you saying you have just JPEG pictures of your pulses? This makes no sense. You have to have the data in order to detect pulses in the data. How can you say that you don't care about the pulse data?
