sequance of differant sine wave

[516]

hi

is there any way to generate a sequance of sine wave with differant amplitude with silent zone between them in labview.

Sure.  Look in the Waveform Generation palette.  There you can build your different sine waves.  (A silent period could just be a zero amplitude sine wave).

Then use the Append waveform function from the Analog waveform palette to append them.

thank you for your help,really i have 6freq with 10 diffrent amp =60 block of signal generation *2 for silent zone =120 block so it,s difficult to put this no. to generate the signal,is there shorter way may be use modulated signal while i don,t know how to do it or any other shorter way.thank again.

You could set up some for loops and use arrays that define your sine wave parameters.  Have the For Loop step through the arrays and append to the existing waveform that you carry from iteration to iteration using shift registers.

thank you i will try this

You could also test this tool http://sine.ni.com/nilex/DisplayLinkAction.do?id=36NILEX. It is called NI analog waveform editor. I think the tool will work 30 days for evaluation.

hi again

there is no evaluation vertion for this tool kit ,any way i used two while loop but they run countiuasly . iwanted them to run only one time but i dont know how to top them after they finish the data for only one time.i attached the file.can you help me

I found the demo here https://lumen.ni.com/nicif/us/evalanlwavedtr/content.xhtml ;). But I guess it more fun to program. It is actually a good learning application for a beginner.
