how can i design a electronic circuit in lab view

[qazi]

i am measuring void fraction (air bubble) in a air water pipe flow . i wish to know can i apply signaling condition by using any of labview controls. where can i find electronic items such as resistors capicators etc in Labview

In labVIEW, signal conditioning is done by using mathematical filtering rather than analog filtering. You don't build filters and other conditioners with resistors and capacitors, you do it with VIs. If you have the full or pro versions, there are many VIs in the analysis palettes. If you have the base package, your choices are more limited.

If you are just trying to see how LabVIEW does things, i would like to recommend the Express VIs as a way to play arround to get what you are after.

I hope that this helps,
