Derivative of analogue signal

[Dimition]

Hello!

I use NI cRIO-9075 and module NI9205.

I need to get derivative from analogue sensor, input AI0. How can i get this?

So, help please to get array from AI0. I have next idea: need to get 10s and 1st value from array, and then :             dxdt= (x10-x1)/t. This infromation into graph wave.

Thanks!

Hi Dimition,

use a shift register…

(Or for longer periods the PtByPt-DataQueue.)
