D/A converter delay transfer function

Hello. How can I add the delay of the digital/analog converter in the circuit? I tried to do it from the transfer function block but I couldn't do it.

That doesn't look like the typical D/A converter .....

But, assuming T is negative you can simulate the delay of -T/2 with a Transport Delay block.

Well, as you've already discovered (exp(s*T/2) can't be entered into a Transfer Fcn block. Why not try what I suggested and see if the result makes sense relative to how you think your D/A block should work. If you're still not sure, I suggest going back to your notes or book and looking up the inverse Laplace transform of that representation of the D/A.
