Undid revision 1225173465 and 1225173581 by Liz (talk) - Huh? They both still on commons at c:File:Hilbert resonator.svg and c:File:Lumped-distributed comparison.png, it looks like you just removed the local copy for reasons that make sense for that but don't make sense for removing from the article

Distributed-element circuits were studied during the 1920s and 1930s but did not become important until [[World War II]], when they were used in [[radar]]. After the war their use was limited to military, space, and [[broadcasting]] infrastructure, but improvements in [[materials science]] in the field soon led to broader applications. They can now be found in domestic products such as satellite dishes and mobile phones.
