"sample and hold" function in LabVIEW?

[chrlum47]

Is there a traditional "sample and hold" function in LabVIEW?

Usage:

Comparing ongoing data point to previous.

I'm sure I could do it with arrays- however I'm wondering if there is a standard sample and hold function.

Hi chrlum,

it's called shift register or feedback node...

oh I forgot about shift registers... Which I am familiar with..

yes I bet that would work thank you

Feedback nodes can be better because they can take up less diagram space.
