build sine wave,sawtooth, square,triangle wave using equation

[student12345]

i need to be able to select a function (wave, square, parabola, exponential) from a ring menu, and show the resulting graph, along with the associate equation.

Hi,
All signal generation VIs use a dll to generate the signal. They do not return the function. You will have to create your own case structure with ring menu wired to the selector terminal and the equation string in each case corresponging to the signal generation VI used in that case.

HI expert..

i am new in a Labview programming and attend some conference and seminar from Labview..

i am trying to simulate a Sine wave,saw tooth wave,triangle wave,square wave using equation same like "simulate signal package in labview, because  but i need to configure all the variable data inside the equation. .. like  x= a sin 2*pi*f*t or x= a sin w*t..

i am using labview 7.0..

can anyone help me please

I believe this is a duplicate post, but here is my response.

I do not have LV 7.0, but an example program that I would look into is the Function Waveform Generation.vi example.  I found it in the example finder for LV 8.2.  If there is a similar function in LV7.0 I think that is your best solution.

Hi Brian,

i  just borrowing and  look into that book LV 8.0,  but i didn't see the example program that you speak about.

can you save into labview 7.0 format please...

The shipping example in 7.0 is called Waveform Generation Using Formula which uses the Formula Waveform funciton on the Analyze>Waveform Generation palettte.

Thanks Dennis for finding that in LV 7.0.

Hi expert,

Thank u very much Brian and Deniss....such a good example....
