回應： How to Plot the Envelope of the resulting signal of 2 random signal？

[Ying88827]

Firstly i add up two random generated siganl to get a final signal.

then，how can i get the envelope of the final signal？and plot it in a graph？

thank you

like the picture i attached.

Hi Ying, instead of attaching a picture taken from your phone, why not upload the actual code? Is it proprietary?

Sorry，im a new user in labview，here is the code

Unfortunately I am using LV 2014 so I cannot view it. Can you backsave it? (Maybe to 2012 so more people can see)

Like this？

Using Hilbert transforms you can get the required envelop. Just it returns only upper envelope. You need some more coding to get also lower envelope.

Do you need something like this?

Thank you so much！

Sorry, I have question again....If I change one of the signal into sawtooth or square wave, the envelope is not that smooth and some peak it detect is not accurate. So how can I fix it?
