You need to do some homework and derive it, there's a
dependence on the pulse shape that you use in your
modulation. It is commonly called the "gain" of the TED,
and it can be derived from the S-curve, which is the expected
output of the TED as a function of the true delay.

Do you have references on the terms I used above?
