How to implement the function ( integration function)" integral(Yn)= Yn-1 + Yn   *  dt  " Please suggest the vi and procedure to build this function

Hi Vika,

start like this:

[Vikaspeddanagiredy]

hi...

    How do you get a sample time dt???

[GerdW]

Hi Vika,

I don't know: "dt" is part of your equation and you should know this input on your own…

Well, you might use a samplerate of your DAQ here. Or you need to calculate dt by subtracting timestamps.

Hi,

        Can you tell me how to calculate delay by subtracting time stamps and how to use sample rate of DAQ.

Thanks in advance

[GerdW]

Hi Vika,

when you set a samplerate to your DAQ task you already know dt as dt= 1/samplerate.

To calc dt based on timestamps is quite easy:

This is all very basic LabVIEW stuff so I recommend to go through all those free online courses offered by NI and to study all the relevant example VIs coming with LabVIEW!

hii

I have implemented the same way as you told. But I am getting Zero as answer everytime . Even Current time is zero and time since 1st jan 1904 is zero

Hi Vika,

I don't believe "Current time" is zero! The only use case when the snippet above will give zero is when you call it more often than 1000 times a second…

Please show your VI or block diagram!

hii,

 It was a silly mistake. I got it. Thank you soo much
