how can I transform the digital waveform into analog waveform, and put the digital waveform display in a analog waveform chart

how can I transform the digital waveform into analog waveform, and put the digital waveform display in a analog waveform chart

Any suggestions would be greatly appreciated.

Thanks,

Have you looked at the Waveform palette? You would have seen Digital to Analog.vi. That's assuming you are using LabVIEW.

Hi Dennis Knutson

   Thanks for your answer,Yes.I have,but it doesn't work like what I want . the program generates three digital waveforms ,which I want to transform into analog waveforms,But The analog waveforms which have been  processed by Digital to Analog.vi,  are not the same as it is displayed in digital diagram,

The software I installed is Labview 8.2, What is the problem I encounter,What I shoud do to acquire the three analog waveforms

The digital waveforms

But the transported waveforms are as following

If I recall, you have to do one signal at a time.

I see,It's very inconvenient ,I have to try this method,since I haven't found other ways.

Thanks for your suggestion
