HOW CAN I DRAW A PARABOLIC WAVEFORM???

[ayesha]

HI..IM USING LABVIEW 7..FOR MY PROJECT I NEED TO DRAW A PAARABOLIC WAVEFORMS HAVING 3 CURVES..i.e., 3 PARABOLAS CONTINUOUSLY..CAN ANYONE HELP ME OUT..PLEASE..

What are your specific questions?  We won't do your homework for you.

This question is way too generic. Where exactly did you get stuck? 🙂

• What kind of "project" is this. Can you give some background?
• Do you know what a parabola is?
• Do you know how to generate a parabola as array or waveform?
• What differs between the three curves?
• Do you know how to graph a single curve?
• Do you know how to draw one parabola, but fail to draw three?
• Do you have problems with the word "continuously"?
• Typically, a parabola gets pretty boring after a while of continous graphing. Should it start over?
• How well do you know LabVIEW?

Why are you typing in all caps? You're freakin me out 

Anyway, go to your funtion pallette then:

 Waveform >> Analog Waveform >> Waveform Generation

Under this menu, look for the function " Formula Waveform . VI "

Using this function, you can graph whatever function you want.

In your case, right click on the input "formula" and create constant.

Then type "t^2" or whatever parabolic function you were yelling about in all caps.

Hi,

Could u please let me know who can I do a parabolic waveform with a vortex of (5, 10) please

[altenbach]

I can!

[Ansam]

May I ask u to send me the block diagram of that. I will be really grateful

[altenbach]

What specific problem is preventing you from doing it yourself?

[Ansam]

I followed all the steps that u mentioned

 Waveform >> Analog Waveform >> Waveform Generation

Under this menu, look for the function " Formula Waveform . VI "

but I do not know who to write the formula in lab view, the parabolic that I want has an equation:-

y = (x-5)^2 + 10

[altenbach]

Just create a ramp pattern (x) over the desired range, apply the formula (y) using plain LabVIEW, and graph on an xy graph.
