Experts, As we know for perfectly matched line insertion loss is due to ohmic & dielctric losses and due to these losses we see loss in rise/fall time as well as loss in amplitude of signal. My question is what actually affects amplitude loss, is it ohmic loss or dielectric loss ? My understanding says, it should be ohmic loss as it comes in series coz dielectric one is shunt loss. If this analogy is correct then a channel having very low ohmic loss but significant dielectric loss will have only changes in rise time but minimal amplitude loss, right ??
