We've been given the problem below for our current assignment
As far as I can recall, I have never seen a transfer function with time units in the function itself, added onto each separate term. I have a good idea on how to handle the delay t_d=25ns, but I have no idea how to handle the delays on each term.
One idea I have had, is noticing the that the term t_d=25ns would imply that we need to find the response at t=25ns. As all other terms have delays in the range of microseconds to seconds, I thought that perhaps this would imply that these signals may not yet have "come into effect", leading to the only term being 100*10^3 s. But this seems like an improper transfer function, and Maple's DynamicSystems package won't accept it.
The title of the problem leads to me thinking that the terms and their delays will affect the phase of the transfer function - but the seconds are causing me so much confusion, that I don't know what to keep and what to leave out, when trying to figure out my response.
