Units of transfer functions

[Delta D]

Hi

I want to implement a first order model using the simulation module of LabVIEW. I'm using a fixed step ODE solver with step size of 0.1s and I have set the simulation loop period equal to the step size (100ms). Do transfer functions have a predefined unit for the value of time constant: s, ms?

Thanks

There are numeruous ways to derive a transfer function. Are you implementing a continuous or discrete transfer function? I'm guessing you are using a discrete transfer function. Inside a simulation loop, that block has two time-related parameters, sample period and sample skew, which are both clearly defined as seconds. Does this answer your question? If not, I'll need more info on what you are doing.

That answers my question!!! I had used a continuous transfer function were I should use the discrete block to sync it with my loop rate and DAQ tasks.

Thanks a lot! 😄
