Adding noise and waveform

[meere]

I'm trying to make a VI that shows how certain types of noise affect a signal. The result is not what I expected, any comments or recommendations to make it better? attached below is the vi

What is not meeting your expectations? And in what way?

I was expecting a signal looking more like this

Use the Signal Processing->Waveform Generation VIs for your noise generation.  They should use the same sampling info as your main signal.

What operation did you use? that addition vi seemed different from thte one I used.. thank you for the help

The Add will show the error terminals when two waveforms are being added together.  You will get an error if the data rates are different.
