Hi, I am trying to define the following transfer function block in Simulink:

12.5*exp(-s)/(s^2+s+6.25)

What should I use in the Simulink library?

Transfer function block with these parameters:

num=12.5
den=[1 1 6.25]

Connected to a Transport Delay block

thanks for responding, how does a transport delay correspond to exp(-s)?
