What is this function

What is the name of the attached function?

Well I haven't seen the exact thing, but my guess is that its a Z transform delay node.

Whatever this is, it is not part of standard LabVIEW. It probably is related to the Z transform delay node as mentioned above.

It could be part of a toolkit or even be a custom tool written by some random programmer. Do you have the actual VI or just a picture? Is there any documentation?

[Shane_White]

Sorry, no VI or documentation.  I'm going off a screenshot.

[Shane_White]

Thank you, Sir.  That is a good place for me to start.

That is the DFD Integer Delay VI, which is part of the Digital Filter Design Toolkit.

Chris, you rock.  Thanks a bunch.

Most toolkits can be recognized by the unique upper part of their icons.

One of these days, a NI intern could create an album of all possible such banners and post it here.... 😉

That's also the reason it is encouraged to keep the label of such VIs as visible.
