Measureing Time Delay of two Waveforms

[Steve_Block]

I noticed that Labview has a number of waveform measurements VIs. I would like to be able to measure the time delay between two waveforms. Does such a vi exist in the tool kit?

Note: I'm using an older version of LabView 2009.

Hi Steve,

you should explain the term "delay" in more detail…

- Each waveform has a t0 part. You can subtract both to get the delay between them…

- When you want to measure delay between certain parts of your waveform you might consider the cross correlation function…

A scope delay between two signals. Just like you would measure a rising/falling edge to a rising/falling edge on an oscilloscope.

Sounds like cross correlation (for arbitrary signals)!

For digital signals you might consider searching edges and subtract their timestamps…
