How to use Transport Delay VI? Please show me some example.

[TOTSAPORN]

I want to delay signal with my selection delay time(example:second,period,number of sample). I saw in LabVIEW have,it have three delay function are 1.Transport Delay 2.Delay Value 3.Unit Delay .Now I take look for Transport Delay VI.I think this function can delay signal with specific time which I want.I tested it by use it to delay sine wavefrom(number of sample=1000,sampling rate =1000Hz),for Transport Delay,I set initize=TRUE,Delay=500. I think the result may sine waveform which same shape of original sine waveform but delay 500 sample after it but the result different from my think. Everyone please recommend me,How to use it?Show me some example.Or please tell me how to delay signal.If can not post picture on the board,mail to me.

Hi TOTSAPORN!

It sounds like you are trying to alter the timing of a waveform. What I would suggest to you is to look at the Waveform palette to explore the different ways of manipulating the waveform datatype. Also, I put together a small example (written in LV 7.1) to delay the waveform graph by 500 samples (500*dt seconds).

Hope this helps!

HI Travis
I have a problem. Now I used LabVIEW7 Express, it can not open your attach file (Wave Offset. VI). I find Waveform offset VI and it example (Waveform Scale and Offset Example.vi), it available in LabVIEW7 Express but its not show the way how delay signal. Please show the example again which written by LabVIEW7 Express or below.
Thanks

Hi TOTSAPORN,

I down-converted the VI to LabVIEW 7.0 and attached it below.

I hope this helps, and good luck with your development!
