Rif.: How To Implement a Transfer Function

[nigeltorque]

Hi everybody..

after a little work i finally find the Transfer Function i was looking for, in my project. Now i have the TF i just have to implement it in labview to condition my input signal; i just find the Discrete Transfer Function .vi included in the "Control & Simulation" package but i am not sure my work is working fine, cause i can't graph the output signal.

As you can see (i have attached my project) the DTF.vi takes as inputs the input signal and the transfer functions (as a string), but i am not sure this is the correct use of the .vi or the best way to implement my transfer function in labview..

Does anyone have any idea or suggestion how can i solve this problem?? I just need to condition the signal input with the transfer function i find..

Thank you!

No one who know hao to use a transfer function .vi??

No one who use the Simulation Module??

Just a transfer function to implement..

Thank You

Hello Nigeltorque,

can you please take a look at the following link?

You would like to see the way that a transfer function is implemented, right? I believe these links will help you.

I see your link and i think that's the way i have to take to implement the transfer function; but i don't want tu use a simulation loop, i think it's better to use a While loop and use the "transfer function" function from the CD Simulation..

I try to implement this .vi in my project.. it's a sort of a filter as you can see in the attchement.. but it doesen't work.. have you an idea of how can i realize the project or where is the mistake??

Thank You
