... Propagation delay (t ). The time required for the device PROP output to reflect a change in the primary current signal. Propaga- tion delay is attributed to inductive loading within the linear IC package, as well as in the inductive loop formed by the primary conductor geometry. Propagation delay can be considered as a fixed time offset and may be compensated. ...
