Editing Signal Cluster

[Edmund.M.Williams]

What are the best tools to use in LabVIEW for signal editing.  Like in removing pieces of signals from beginning and end, or adding signals at beginning or end of the signal cluster array.  Or is this just a "Y" parameter operation for Signal Cluster?

Hi Edmund.M.Williams,

Could you clarify what you mean by Signal Cluster?

It sounds like you might be referring to a waveform. In this case, you'll likely be using Array Functions to modify the Y parameter to add/remove pieces. See the link below for more information:

This is what the Cluster looks like:

It looks like the only thing that can be manipulated concerning the signal is the Y array.  changing the "dt" will change the frequency, which is undesirable.

Hi Edmund,

This is what the Cluster looks like:

So you are using a waveform (as can be read in the label of that control)…

Did you read the link on waveforms and understand what they represent and are used for?

It looks like the only thing that can be manipulated concerning the signal is the Y array. changing the "dt" will change the frequency, which is undesirable.

Well, you can manipulate 3 items: t0, dt and that Y array. (You can edit even more items, as waveforms also carry attributes.)

Editing those 3 items can be useful in many situation, even when you declare it as "undesirable"…

There is a palette full of waveform functions.

There is a signal prcessing palette,also able to handle waveforms.

You can unbundle the Y array and manipulate is using array or other math/signal processing functions.

You can do anything you like with those sample data!
