Editing Bridging loss

{{no footnotes|date=March 2013}}
'''Bridging loss''' is the loss, at a given [[frequency]], that results when an [[Electrical impedance|impedance]] is connected across a [[transmission line]].<ref>{{Cite book|title=Communications Standard Dictionary|last=Weik|first=Martin|publisher=Van Nostrand Reinhold|year=1989|isbn=9781461566748|location=New York|pages=109}}</ref> It is expressed as the ratio, in [[decibel]]s, of the [[signal (information theory)|signal]] [[power (physics)|power]] delivered to a given point in a [[system]] downstream from the bridging point prior to bridging, to the signal power delivered to the given point after bridging. The term is introduced because return loss is not applicable to the high-impedance input conditions.<ref>{{Cite book|title=Newnes Telecommunications Pocket Book|last=Edis|first=E.A.|last2=Varrall|first2=J.E.|publisher=Butterworth-Heinemann|year=1997|isbn=0750603070|location=Oxford|pages=247}}</ref> The term is also used in telephone practice and is synonymous with the insertion loss that results from bridging an impedance across a [[Telecommunication circuit|circuit]].<ref>{{Cite book|title=Van Nostrand's Scientific Encyclopedia|last=Considine|first=Douglas|last2=Considine|first2=Glenn|publisher=Springer Science+Business Media|year=1995|isbn=9781475769203|location=New York|pages=470}}</ref>
