When I convert a f-domain channel to differential t-params (TDD11), I notice the impedance rising along a transmission line segment as if the tline is predominantly inductive. This tends to bias the impedance higher for features towards the far end. The single-ended f-domain channel includes the normal 50 ohm terminations. Is this a real phenomena? How is it explained? Thanks.
