Help--Easy problem: wavefrom accumulation

[wuligang]

Hi,

I have a really simple problem.

I am using Labview to acquire and display waveforms from a digital scope.

Right now, I have got the waveform and can display wavefroms one by one.

I am using a while loop, initialize the scope before loop, acquire and display in loop

close scope after loop.

What I want is the display of a sum of 100 waveforms. I guess that I need some

stack or memory to do this but I am really new to Labview and don't how to make full

use of the help file. Could anyone give me some help on how to solve this kind of

problem?

Easiest would be to keep your signal in a shift register and add the new signal at each iteration to it. For display, divide it by N.

See attached simple example. Modify as needed. 🙂

Aha, That's exactly what I want!!

Thanks a lot !!
