For my project

[Nede]

Hi, for my project i have to generate random noise of a violin at 196 hz 294 hz 440hz and 660 hz. I also have to generate 2 sounds optionally and the signals generated in each case can also be viewed graphically in the fron pannel. Please help me.

The waveform palette has functions to generate waveforms.  You can generate several waveforms and add them together.  There are also ones for random noise.

You can wire the waveforms to waveform graphs to view them.

Get started, and post your VI when you get stuck or have further questions.

Ok. I'll try, i'm new to labview and it's kind of hard for me to make this project, since no one explained it to me really good. Thank you

Someone told me to use this one but still, i have to put some things in it.

A violin has a significant amount of harmonics and is better approximated by a triangular wave.

In order to help, you probably need to give much more detailed specifications.

What is "random"? (Occurrence? Duration? Frequency? Volume?)

What are the "2 sounds"? (Polyphonic? Stereo?) Are these separate or related to the violin?
