Modulating a square wave

[viswa]

Hello all,

                    I am trying to generate a composite signal shown in figure attached to this post using a single analog output channel using PCI6221 board. At the moment i can generate parts of composite signal independently. I am using LV 8.2. 

Is there any way to mix two independent signals to genearate signal shown in the image???? Any clue would be greatly appreciated!!!!

regards

 Hi,

you mean this type of signal?

Your 'mix' means add 😉 

You can simply use the numeric add to add arrays element by element or you can even add waveforms. Doupleclick the Tones and Noise Waveform.vi and look how it's done. (If you want to modify it, save it first AS A COPY !  )
