continuous sinewave signal

[mauro81]

hi,i need to generate a continuous sinewave signal which have amplitude and frequency continuously variable (without stopping the output generation),may you help me?thanks

I have found no place where you can change the amplitude.  Attached is an example of changing the frequency.  You can vary the desired frequency while it is running.  LV7.1

Sorry but i haven't the labview 7.1.i can use only 6.1-7 labview versions.

may you send me an aqual example for one of these labview versions?

regards,

Mauro

Hi Mauro,

Just go to labview examples and you will find a VI called "Function generator.VI" (or got to search tab and type this name to find it)

This Vi will not only generate the selected function but also permits you to change the type of signal, its amplitude, frequency, offset, phase etc on the fly( without stopping the VI)

Hope this helps

Hi,

Here is the VI i have spoken about in previous post

In LabVIEW 7.0

Here is a copy as LV7.0

I am using Realtime frequency.vi for LabVIEW 7.1...It works great, but how can I make it so the amplitude is continuously variable as well?  Thanks!

There is no way that I know of.
