i have transfer function and i want to simulate it in labview and the input to the function is square wave,how can i simulate this transfer function. i want exapmle for this

[st]

i want an example and explanation of simulating transfer function with squrae wave input , and i want a graph of the output.
send answer to my mail

you want things, but you don't give your name or real e-mail, so my answer
will be short (it's sunday...) :

Hi,
If I've got the problem you have the input signal S_in(t) and the transfer function of the system H(t) and you want to find the output signal S_out(t).
So the output will be proportional to the convolution of S_in(t) and H(t):

S_out(t) ~ Conv(S_in(t), H(t)).

You can find the convolution VI at
'Functions->Analyze->Signal Processing->Time Domain->Convolution.vi"

Good luck.

There is also a Transfer Function VI that ships with the LabVIEW PID toolkit. I have always found this one the easiest to use.

Thanks Brandon, your tip is a great help to me.
