[simpson67]

Hello, everyone.

I wanna get above red waves that is the Evnvelope wave of some input signals.

But I don't know what it can.

Now, I am using DAQ(NI USB-6259BNC ) and Labview 2010 evaluate ver.

Exactly I woder that getting above red envelope is possible.

some people said if I purchase toolkit or another instrument, implementation of ET(Envelope Tracking) technology will be possible.

And they said it will be possible using hillbert transform on labview. I don't know...

If you have any example using DAQ , plz upload for me. thanks.

Have a nice day.
